## Basics of Square Root and Radical Symbol: Rational and Irrational Numbers

An important area to learn in mathematics is square roots. In mathematics, we calculate powers; we multiply numbers by squaring or cubing them. Square roots are a relative of powers. If you have learned the concept of powers, you can understand square roots. Square roots also use a symbol called root symbol (or radical symbol). […]

## How to Solve Linear Functions: Graph of Slope/Intercept and Intersection

After learning the definitions and concepts of direct proportion and inverse proportion in mathematics, the next step to study is linear functions. Similar to the graph of direct proportional, it is linear functions that if the value of $x$ increases, the value of $y$ increases in the same ratio. In linear functions, there are two […]

## Simultaneous Equations: Addition Method and Substitution Method

In mathematics, we may use two equations to solve a calculation problem. If there are two unknown numbers in the equation, we cannot find the answer. However, if there are two equations, we can find the answer even if there are two unknown numbers in the equation. A combination of two or more equations is […]

## Direct and Inverse Proportion: Coordinates and Equations in Graphs

An important concept in mathematics is direct proportion and inverse proportion. We frequently use the words direct proportion and inverse proportion in our daily lives. Direct proportion and inverse proportion are familiar to us and are concepts that everyone uses. The concept of direct proportion and inverse proportion is used in many situations. When studying […]

## Linear Equations: Transposition and Tips for Solving Word Problems

Math calculations frequently involve the use of letters instead of numbers. By using algebraic expressions, we can easily solve math problems. One of the most important areas of algebraic expressions is linear equations. Linear equations are frequently used in daily life calculations and are the basis of mathematics. Even if there is a number you […]

## Expansion by Factoring Formulas and Polynomial Factorization

In mathematics, we learn algebraic expressions using the alphabet. We use symbols to perform calculations such as addition, subtraction, multiplication, and division. Parentheses are often used in math calculations. When multiplying parentheses by parentheses, we use factoring formulas. Once you learn factoring formulas, you will also be able to factorize them. Factorization is the way […]

## Multiply and Divide Polynomials, Distributive Property, and Substitutions

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 […]

## Algebraic Expressions of Monomials and Polynomials: Addition and Subtraction

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 […]

## Commutative Property and Associative Property: Addition and Multiplication in Math

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 […]

## Four Arithmetic Operations of Positive and Negative Numbers: Priority of Math Calculations

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 […]
