College Algebra and Problem Solving

College Algebra Math Courses

College Algebra and Problem Solving is an essential course for those looking to venture into any math-related course in tertiary learning institutions.

Renowned universities such as the Arizona State University, Harvard, MIT, the University of Michigan and many more, offer it as an introductory course to advanced algebra. But if your schedule does not allow you to attend classes, you can take it online.

With this course, you will get to apply algebraic solutions to everyday math problems. You will also study quadratic and linear functions, rational functions, polynomial functions, logarithmic functions, exponential functions, and the systems of linear equations.

The main goal of the course is to improve students’ problem-solving skills through discussions on the core concepts of each topic.

EdX is the best online site to take a College Algebra and Problem-Solving Course. It uses a self-paced curriculum that allows you to study at your own speed depending on how quickly you master the various concepts.

This adaptive approach allows students to fully understand each concept before they move on to the next one. This is achieved through the use of the ALEKS learning system which personalizes coaching and student progress.

EdX’s College Algebra and Problem Solving course is tailored to the MAT 117 College Algebra course offered at the Arizona State University. One of the perks of learning college algebra through their platform is that the course is enlisted under the Global Freshman Academy (GFA), meaning it is eligible for credit transfer.

Also, their curriculum meets all the stipulations set out by the University’s Mathematical Studies (MA), so you can be sure you are investing your time and effort in a worthwhile course.

Introduction to Geometry

Introduction to Geometry math courses

Over 2000 years ago, a Greek mathematician invented a way to calculate the size of the earth with nothing but a handful of facts about circles, angles, and lines. This marked the beginning of geometry, a course that has done nothing but revolutionize math. 

Under Introduction to Geometry, learners are introduced to angles, triangles, circles, polygons, and tons of other mathematical shapes. Tutorials trace geometry to its ancient origins and explain how things like angles and lines came to be, as well as how to measure them. Afterward, students are taken through more advanced theorems, including 2 and 3-dimensional shapes. 

By the time you are done with this course, you will be familiar with concepts such as finding the area of a triangle, counting stones in the Great Pyramid of Giza and estimating the size of our planet. However, you need to have a firm grasp of algebra before you begin learning geometry. 

School Yourself is one of the best online sites to learn geometry. The institution offers the course for free. The whole course takes about 14 weeks to complete. 

However, you can take a shorter or longer duration, thanks to their self-paced program that allows you to have control over your learning progress.  They also allow you to review tutorials that you might have missed. 

If you don’t mind paying a few bucks for a course, you could try taking the course at Art of Problem Solving (AoPS).

They have an interactive learning platform, and they teach Introduction to Geometry using Richard Rusczyk’s textbook. 

Richard has won the U.S. Mathematical Olympiad several times, making him well-versed in the subject. Topics covered in his book include congruent triangles, circles, similar triangles, quadrilaterals, 3D geometry, funky areas, transformations, and power of a point. 

The course is expertly structured to stimulate new ideas and inspire learners. It contains tests for each section to allow students to gauge their understanding before proceeding to a new chapter. 

Even better, the textbook provides answers to all self-assessment tests. This reduces a learner’s dependency on tutors, hence, enhancing their problem-solving skills. The only limitation of the AoPS is that it is not a self-paced program. 

Precalculus Course 

Precalculus Course math courses

Precalculus is a math course that builds on your trigonometry knowledge. 

Trigonometry is a branch of math that specializes in the study of triangle lengths and angles. However, the applications of trigonometric functions in real-life situations extend beyond the study of angles and triangles, and here’s where precalculus comes in. 

Precalculus is a pre-university preparatory course for those seeking to enroll for the Single Variable Calculus course. 

The course is part of Arizona State University’s Global Freshman Academy (GFA). This means you can transfer three ASU credits to your degree once you’ve completed the course through their website. 

The course, dubbed MAT 170 at Arizona State University, focuses on quantitative reasoning and functions. It equips learners with the skills needed to describe the characteristics and behaviors of logarithmic, linear, rational, exponential, trigonometric, and polynomial functions. 

The Arizona State University online platform offers this course through a personalized learning experience. This is achieved through the use of the ALEKS education system, which facilitates self-paced learning and individualized coaching. 

With a self-paced learning system, the University doesn’t have a specified duration for the course. 

However, you cannot take more than a year on precalculus, which is pretty fair considering that most people complete it less than eight months. 

The University of California is another great platform for learning precalculus online. Like the Arizona State University, they allow students to study in a self-paced program, although you can still enroll for session-based classes. 

Session-based tutorials have strict deadlines but allow you to complete the course faster. In case you fall behind on these classes, you can always switch to another session, along with all your progress. 

These two institutions offer topnotch online precalculus tuition. But before you enroll in this course, you need to have excellent mastery of basic algebraic concepts such as exponent rules and radicals, factoring, and equation solving. 

Therefore, you may want to take an algebra course before your enroll for precalculus. You will also need some background knowledge of trigonometry. 

Arithmetic Courses

Arithmetic Courses math courses

Although most of these courses are designed for kids, no one is too old for arithmetics. By using numbers in calculations, you will be boosting your cognitive performance. There are tons of websites offering this course, but not all can provide astute guidance. 

At the moment, the best site to learn arithmetic is MathABC. It explains math problems with the simplest instructions possible, lets students practice what they learn through quizzes, and uses colorful images to illustrate complex math problems. 

The learning process is as fun as it is informative, a feature that eliminates boredom. It also explains theories brilliantly and demonstrates them with calculations. 

Although MathABC is dedicated to teaching math courses to kids from kindergarten to sixth grade, adults can still use it to up their numbers game. You have nothing to lose since all the classes here are free. 

Khan Academy is another great site to teach kids and adults the basics of arithmetics. The online school is known for providing some of the most comprehensive courses, and arithmetic is no exception. They have everything you need to master this course, from simple addition and subtraction lessons to those involving decimals. 

One of the advantages of learning at Khan Academy is that all their syllabuses are accredited. Their lessons and tutorials are well-structured to ensure systematic and progressive learning, and their website is so user-friendly that a kid can use it alone. 

Arithmetic Game and are other great sites to consider. 

Discovery Precalculus: A Creative and Connected Approach 

Discovery Precalculus math courses

Discovery Precalculus deepens your understanding of calculus by building on the knowledge of graphs, geometry, and algebraic equations that you learned in high school and pre-university calculus, preparing students for complex concepts taught at the university level. 

Precalculus and Discovery Precalculus may seem similar, but the two are quite different. While the precalculus course simply introduces students to varsity-level calculus, Discovery Precalculus helps learners develop logical math arguments and support them. 

It leans more on the application of calculus in solving mathematical problems than simply teaching concepts. It also encourages learners to think more independently using what they learn from the course, rather than just grasp the mechanics of calculus. 

EdX offers this course in conjunction with the University of Texas through their online platform. The lessons and tutorials offered on the site are tailored and taught by Mark L. Daniels, an instructor from the affiliated university. 

As it is with most courses offered on EdX, students are allowed to learn at their own pace. All thanks to the self-paced learning system. However, there is a suggested course duration of fifteen weeks, which is more than enough time you’ll need to complete this simple course. 

The lessons are free of charge, although you might have to pay a few bucks for certification. 

Statistics Course 

Statistics Course math courses

This is more of an advanced level course for college seniors, but you can still take the course through online platforms at any stage of your post-high school education. 

Statistics involves collecting data, analyzing it, and drawing conclusions. In other words, it is the art of making sense of numerical data. 

There are a number of online platforms that offer statistics courses. YouTube channels are a good way of grasping basic concepts on statistics. One of the best YouTube channels in this regard is Statistics 101. Despite being free, the channel does a brilliant job where explaining complex concepts is concerned. 

Their tutorials are so easy to understand. You don’t need an extensive background in math to understand what the tutors are teaching. Their videos are short—about 25 minutes long—and make good use of graphs and diagrams to illustrate complex concepts. 

Another great site to take a statistics course for free is Stat Trek. It may not be the most popular site, but its tutorials are among the most exhaustive lessons you can find online. 

Even better, the site offers free learning tools including a probability calculator and a worksheet. Practice tests are also available to help you gauge your understanding and progress. 

Trigonometry Course

Trigonometry Course  math courses

Trigonometry course is usually taken after a geometry course. 

The two are closely related, but different. Geometry is more about the measurement of angles, while trigonometry focuses on using the values collected for computational purposes. 

Being a computational course, trigonometry is best learned through applications and graphical illustrations. No site does this better than Dave’s Short Trig Course. Lectures are presented in the simplest form possible and are often accompanied by graphs. 

For best results, combine the Dave’s Short Trig Course with practice tests from Varsity Tutor. This site offers the most comprehensive practice tests you can find online. Their illustrations are properly laid out for easy learning. 

Math Gets Better With Lots of Practice  

There’s no denying that math is a challenging subject. Even with great tutors, you will need tons of practice to master various concepts. 

So don’t just take a lesson and expect to grasp everything you learned. Go the extra mile. Revisit what you learned, do practice exercises on your coursework, assess yourself with tests and quizzes, find a study buddy. Anything that works well for you. 

Most importantly, have fun with numbers!
