Understanding Numbers and Operations

Arithmetic operations are the building blocks of math. They include addition, subtraction, multiplication, and division. Mastering these allows you to tackle more complex problems with confidence.

Addition & Subtraction

Adding means combining two or more numbers to get a total. Subtraction finds the difference between numbers.

• \( 15 + 27 = 42 \)
• \( 58 - 29 = 29 \)

Multiplication & Division

Multiplication is repeated addition. Division splits a number into equal groups.

• \( 6 \times 7 = 42 \)
• \( 56 \div 8 = 7 \)

Real-World Applications

You use these operations every day—calculating change, splitting bills, or doubling recipes!

Quick Tips
