Order of Operations Basics

Front

What is the Order of Operations?

Back

A set of rules that determines the sequence in which calculations are performed in a mathematical expression.

Front

What does PEMDAS stand for?

Back

Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Front

What operation do you perform first in the expression 8 + 2 × 5?

Back

Multiplication (2 × 5 = 10), then Addition (8 + 10 = 18).

Front

In the expression 3 + (4 × 2), which operation is performed first?

Back

Parentheses (4 × 2 = 8), then Addition (3 + 8 = 11).

Front

True or False: In the expression 6 ÷ 2 + 3, you perform division before addition.

Back

True.

Front

What is the result of the expression 5 × (3 + 2)?

Back

25 (first calculate 3 + 2 = 5, then 5 × 5 = 25).

Front

Which operation is performed first in the expression 10 - 4 ÷ 2?

Back

Division (4 ÷ 2 = 2), then Subtraction (10 - 2 = 8).

Front

What is the value of the expression 2 × (3 + 5) - 4?

Back

10 (first calculate 3 + 5 = 8, then 2 × 8 = 16, and finally 16 - 4 = 12).

Front

In the expression 12 ÷ 4 × 2, which operations do you perform first?

Back

Both Division and Multiplication are performed from left to right (12 ÷ 4 = 3, then 3 × 2 = 6).

Front

What is the result of 7 - 3 + 2?

Back

6 (perform Subtraction first: 7 - 3 = 4, then Addition: 4 + 2 = 6).
