Basic Concepts

Numbers and Operations

Understanding Numbers

Numbers are the foundation of all mathematics. In GED Math, you'll work with whole numbers, fractions, decimals, and percents.

Types of Numbers

  • Whole Numbers: 0, 1, 2, 3, ...
  • Integers: ... -3, -2, -1, 0, 1, 2, 3, ...
  • Rational Numbers: Numbers that can be written as a fraction.
  • Irrational Numbers: Numbers that cannot be written as fractions (like \( \pi \) or \( \sqrt{2} \)).

Basic Operations

The four basic operations are addition (+), subtraction (−), multiplication (×), and division (÷). Mastering these is crucial for solving more complex problems.

Working with Fractions and Decimals

  • To add or subtract fractions, make sure the denominators are the same.
  • To multiply fractions, multiply the numerators and denominators.
  • Converting decimals to fractions and percents helps compare values.

Estimation and Mental Math

Estimation is a useful skill for checking your answers quickly and making smart guesses when needed.

Real-Life Applications

Numbers and operations help you with tasks like budgeting, measuring, and cooking.

Examples

  • Adding \$12.50 and \$7.30 to find the total cost of groceries.

  • Dividing a pizza into 8 equal slices and figuring out how many each person gets.

In a Nutshell

Numbers and operations are the building blocks of math, used in every aspect of daily life.
