A mathematical equation that uses the alphabet is an algebraic expression. In junior high school and high school math, we need to understand how to use algebraic expressions because they are almost always used in math. An equation that consists of several algebraic expressions is called polynomials. In polynomial calculations, multiplication and division are frequently […]

In mathematics, we use letters to perform calculations. This is called an algebraic expression. Before learning the algebraic expression, calculations are done using only numbers. However, after learning algebraic expressions, math is mainly done by using the alphabet. Algebraic expressions have rules. Therefore, you have to learn how to use algebraic expressions. There are also […]

When you study mathematics, you may be taught about the commutative property (or commutative law) and the associative property (or associative law). The commutative property and the associative property are taught in elementary or junior high school. The commutative property and the associative property are valid for addition and multiplication. The commutative property and the […]

After learning addition, subtraction, multiplication, and division for positive and negative numbers, students need to be able to calculate expressions that mix each of them. Addition, subtraction, multiplication, and division are collectively called the four rules of arithmetic. In mathematics, we study the four rules of arithmetic (four arithmetic operations). After learning about positive and […]

When learning negative numbers, many people get confused. This is because when you multiply or divide different signs, the signs change. In addition, when you multiply negative by negative, the sign becomes positive. Why does this happen? Few people can explain this reason. However, in order to understand mathematics, we need to solve the question […]

When you learn math, you have to understand negative numbers. Unlike when you were learning only positive integers, learning the concept of zero and addition and subtraction will allow you to perform complex calculations. It may seem strange to you that there are numbers less than zero. However, we use negative numbers in many aspects […]
