Order of Operations (no exponents)

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. The common acronym to remember this order is PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Front

In the expression 10 - 4 ÷ 1 x 5, which operation should be performed first?

Back

Division should be performed first, according to the order of operations.

Front

True or False: Addition always comes before subtraction in the order of operations.

Back

False. Addition and subtraction are performed from left to right, depending on which comes first.

Front

What is the result of (7 + 41) ÷ 2 – 15?

Back

The result is 9.

Front

How do you simplify the expression 7x(7-4)÷3?

Back

First, calculate the parentheses: 7-4 = 3. Then, multiply: 7x3 = 21. Finally, divide: 21÷3 = 7.

Front

What is the result of the expression 25 - 14 + 3?

Back

The result is 14.

Front

What does the acronym PEMDAS stand for?

Back

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

Front

In the expression 8 + 2 x 5, which operation is performed first?

Back

Multiplication is performed first, so the expression simplifies to 8 + 10 = 18.

Front

What is the result of the expression 12 ÷ 4 + 3 x 2?

Back

First, divide: 12 ÷ 4 = 3. Then, multiply: 3 x 2 = 6. Finally, add: 3 + 6 = 9.

Front

If an expression has both addition and subtraction, how do you determine which to perform first?

Back

You perform addition and subtraction from left to right, depending on which comes first in the expression.
