Order of Operations

Front

What is the order of operations in mathematics?

Back

The order of operations is a set of rules that determines the sequence in which calculations are performed. It is often remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Front

What does the P in PEMDAS stand for?

Back

P stands for Parentheses. It indicates that calculations inside parentheses should be performed first.

Front

What does the E in PEMDAS stand for?

Back

E stands for Exponents. It indicates that exponentiation should be performed after parentheses.

Front

What does the M in PEMDAS stand for?

Back

M stands for Multiplication. It indicates that multiplication should be performed after parentheses and exponents.

Front

What does the D in PEMDAS stand for?

Back

D stands for Division. It indicates that division should be performed after parentheses and exponents, and it is done from left to right.

Front

What does the A in PEMDAS stand for?

Back

A stands for Addition. It indicates that addition should be performed after parentheses, exponents, multiplication, and division.

Front

What does the S in PEMDAS stand for?

Back

S stands for Subtraction. It indicates that subtraction should be performed last, after all other operations.

Simplify the expression: 2 + 3 × 4.

Back

14 (First, multiply 3 × 4 = 12, then add 2 + 12 = 14).

Front

Simplify the expression: (5 + 3) × 2.

Back

16 (First, calculate inside the parentheses: 5 + 3 = 8, then multiply: 8 × 2 = 16).

What is the first step in solving the expression: 6 + 2 × (3 + 1)?

Back

The first step is to solve the parentheses: 3 + 1 = 4.
