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 (3 + 5) x 2?

Back

You perform the addition inside the parentheses first, so 3 + 5 = 8.

Front

Calculate: 8 + 2 x 5

Back

You do the multiplication first: 2 x 5 = 10, then add: 8 + 10 = 18.

Front

What is the result of 10 - 4 ÷ 2?

Back

You perform the division first: 4 ÷ 2 = 2, then subtract: 10 - 2 = 8.

Front

In the expression 6 + 2 x (3 - 1), what do you calculate first?

Back

You calculate the expression inside the parentheses first: 3 - 1 = 2.

Front

What is the value of 12 - 4 x 2?

Back

You perform the multiplication first: 4 x 2 = 8, then subtract: 12 - 8 = 4.

Front

Which operation comes first in the expression 5 + 3 x 2?

Back

Multiplication comes first, so you calculate 3 x 2 = 6, then add: 5 + 6 = 11.

Front

What is the result of (7 x 5) + (6 x 4)?

Back

You calculate each multiplication first: 7 x 5 = 35 and 6 x 4 = 24, then add: 35 + 24 = 59.

Front

What is the value of 2 x 9 ÷ 3?

Back

You perform the multiplication first: 2 x 9 = 18, then divide: 18 ÷ 3 = 6.
