Frequently Asked Questions
What is arithmetic?
Arithmetic is the oldest and most fundamental branch of mathematics, dealing with basic operations on numbers: addition, subtraction, multiplication, and division. It also covers concepts like fractions, decimals, percentages, and number properties.
What is the order of operations?
The order of operations (PEMDAS/BODMAS) specifies the sequence for evaluating expressions: Parentheses first, then Exponents, then Multiplication and Division (left to right), then Addition and Subtraction (left to right).
