What is the Order of Operations?

Back

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

What does 'P' in PEMDAS stand for?

Back

The 'P' in PEMDAS stands for Parentheses. It indicates that calculations inside parentheses should be performed first.

Front

What does 'E' in PEMDAS represent?

Back

The 'E' in PEMDAS represents Exponents. It indicates that any exponentiation should be performed after parentheses but before multiplication and division.

Front

What operations are performed after Parentheses and Exponents in PEMDAS?

Back

After Parentheses and Exponents, Multiplication and Division are performed next, from left to right.

Front

What operations are performed last in the Order of Operations?

Back

Addition and Subtraction are performed last in the Order of Operations, from left to right.

Front

Solve: 3 + 5 × 2

Back

3 + 5 × 2 = 3 + 10 = 13 (Multiplication first, then addition).

Front

Solve: (4 + 6) × 2

Back

(4 + 6) × 2 = 10 × 2 = 20 (Parentheses first, then multiplication).

Front

Solve: 8 - 3 + 2

Back

8 - 3 + 2 = 5 + 2 = 7 (Perform from left to right).

Front

What is the result of 2 + 3 × (4 - 1)?

Back

2 + 3 × (4 - 1) = 2 + 3 × 3 = 2 + 9 = 11 (Parentheses first, then multiplication, then addition).

Front

What is the importance of the Order of Operations?

Back

The Order of Operations is important because it ensures that everyone calculates expressions in the same way, leading to consistent and correct results.
