Arithmetic is where mathematics begins for most people. It covers addition, subtraction, multiplication, and division — the four operations that turn numbers into useful tools. Without them, you cannot balance a checkbook, measure ingredients, or calculate a tip. The word comes from Greek arithmos, meaning number.

Beyond the basics, arithmetic includes fractions, decimals, percentages, and negative numbers. It also deals with order of operations, the rules that decide whether you add or multiply first. These rules matter. Get them wrong, and a spreadsheet gives you nonsense.

Arithmetic is not just for school. Carpenters use it to cut angles. Nurses use it to dose medication. Shoppers use it to compare unit prices. It is the foundation on which algebra, geometry, and statistics are built. A student who struggles with arithmetic will find higher math frustrating, not because the concepts are impossible, but because the tools are missing.

Core operations

• Addition: combining quantities
• Subtraction: finding the difference
• Multiplication: repeated addition
• Division: splitting into equal parts

Practice builds speed and accuracy, but understanding why the operations work matters more than rote memorization.
