Numeracy is the ability to understand and use numbers. In this course, you will improve your numeracy and your ability to perform four basic operations: addition, subtraction, multiplication, and division. With these operations, you will use not only whole numbers, but also integers, fractions, decimals, variables, and algebraic expressions. If those terms are not familiar to you, don’t worry! You will get to know them as you go. You will also learn to use data, functions, and graphs to analyze information and solve problems.
