Key Concepts

Order of Operations

This key concept dictates the sequence in which arithmetic operations must be performed to arrive at a correct result. It involves following specific rules (commonly remembered as PEMDAS or BODMAS) that prioritize calculations in parenthesis, then exponents, followed by multiplication and division (from left to right), and finally addition and subtraction (from left to right).

Operator Precedence

Operator precedence is the hierarchy used to determine which operations are performed first in an expression that contains multiple different operators. In expressions without parentheses, multiplication and division are performed before addition and subtraction, ensuring consistent and unambiguous results.
