Division is an inverse operation to multiplication and it works to form groups or distribute them evenly. This post will show how to operate both exact and inexact division. When we are doing division, we can be given two situations: to form equal groups and be left with zero remainder (exact division), or to form groups […]

In this post, we are going to learn how to multiply fractions (two or more). To do this, we only have to follow these steps: Simplify fractions: Any numerator can be simplified with any denominator. Multiply fractions in a line: Multiply the denominators to obtain the final denominator and multiply the numerators to obtain the […]

Did you know that the commutative property can help us solve an operation faster? Today we will look at the commutative property of addition and multiplication. The commutative property tells us that the result of an addition or multiplication is always the same, regardless of the order of the elements with which it operates. Let’s […]
