Lesson notes
Addition
Addition combines amounts. Example: 238 + 145 = 383.
Subtraction
Subtraction finds a difference or remaining amount. Example: 500 − 176 = 324.
Multiplication
Multiplication is repeated addition. Example: 7 × 8 = 56.
Division
Division shares an amount into equal groups. Example: 72 ÷ 9 = 8.
Order of operations
Use BODMAS: Brackets, Orders, Division and Multiplication, Addition and Subtraction. Example: 3 + 4 × 2 = 11.
Worked example
Calculate 48 ÷ 6 + 3. Do division first: 8 + 3 = 11.
