Understanding Numbers

Numbers come in all shapes and sizes! From counting your favorite snacks (natural numbers) to dealing with temperatures below zero (negative numbers), understanding numbers is key to solving math problems.

Types of Numbers

• Whole numbers: 0, 1, 2, 3, ...
• Integers: ..., -3, -2, -1, 0, 1, 2, 3, ...
• Fractions: Pieces of a whole, like \( \frac{1}{2} \)
• Decimals: Another way to show parts of a whole, like 0.5

Basic Operations

Add, subtract, multiply, and divide with all kinds of numbers. Don't forget the order of operations (PEMDAS): Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.
