6.7A - Order of Operations

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 should be performed first in the expression 5 + 3 × 2?

Back

Multiplication (3 × 2 = 6), then Addition (5 + 6 = 11).

Front

In the expression 8 + (3 - 1) × 4, what should be calculated first?

Back

The operation inside the parentheses: (3 - 1) = 2.

Front

What is the result of 6(2)?

Back

12 (the parentheses indicate multiplication).

Front

Solve: 12 - 4 + 3 × 2 = ?

Back

The answer is 14 (first calculate 3 × 2 = 6, then 12 - 4 + 6 = 14).

Front

What is the value of 2 + 3 × (8 - 5)?

Back

11 (first calculate inside the parentheses: 8 - 5 = 3, then 3 × 3 = 9, and finally 2 + 9 = 11).

Front

What is the result of 5 × 2 + 10 ÷ 2?

Back

15 (first calculate multiplication and division from left to right: 5 × 2 = 10, then 10 ÷ 2 = 5, and finally 10 + 5 = 15).

Front

What does it mean to multiply and divide from left to right?

Back

It means that when you have both multiplication and division in an expression, you perform them in the order they appear from left to right.

Front

Solve: 4 + 6 × 2 - 3 = ?

Back

The answer is 11 (first calculate 6 × 2 = 12, then 4 + 12 - 3 = 13).
