Fear fractions no more. And learn whether to add first or multiply first in a string of operations. Whether you are struggling with basic math functions in a course today, you are taking a new job that demands understanding of math, or you simply need to review or remember some part of basic math, this course will bring you up to speed. Learn to really understand addition, subtraction, multiplication, and division; know how to calculate and move among decimals, fractions, and percents; figure out ratios and proportions like a pro; and learn to use a calculator for basic math functions.
This course deals with the nuts and bolts of Math. Students will become equipped with a solid foundation of the mathematical tools required to solve more complex mathematical operations. This course would benefit any student (regardless of age) who requires help understanding basic math skills in order to pass a placement test, a course, a specific job, or a review or brush up on math skills.
No previous education is required though understanding lesson material assumes students at least have a 7th grade reading level. Lessons will focus on the steps involved in adding, subtracting, multiplying, dividing as well as the order of operations. In addition this course will focus on the various forms of numbers such as fractions, decimals, percents, radical signs, absolute value signs exponents, ratios.
