Math Lesson 1: Basic Arithmetic

Introduction to Basic Arithmetic

In this lesson, we'll learn about the four basic arithmetic operations: addition, subtraction, multiplication, and division. These operations are the foundation of mathematics and are used in everyday life.

Addition (+)

Addition is the process of combining two or more numbers to get a sum. For example, 2 + 3 = 5.

Exercise: Addition

Try adding these numbers:

+ =

Subtraction (-)

Subtraction is the process of taking away one number from another. For example, 5 - 2 = 3.

Exercise: Subtraction

Try subtracting these numbers:

- =

Multiplication (×)

Multiplication is repeated addition. For example, 3 × 4 means adding 3 four times: 3 + 3 + 3 + 3 = 12.

Exercise: Multiplication

Try multiplying these numbers:

× =

Division (÷)

Division is the process of splitting a number into equal parts. For example, 8 ÷ 2 = 4 because 8 can be split into two groups of 4.

Exercise: Division

Try dividing these numbers:

÷ =
