Easy Order of Operations Flashcard

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 acronym PEMDAS is often used to remember the order: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What does PEMDAS stand for?

Back

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

How do you solve an expression with both multiplication and addition?

Back

According to the order of operations, you should perform multiplication before addition. For example, in the expression 4 + 3 x 2, you would first calculate 3 x 2 = 6, then add 4, resulting in 10.

What is the result of the expression 9 + 6 x 9 + 4?

Back

The result is 67. First, calculate 6 x 9 = 54, then add 9 + 54 + 4 = 67.

What is the result of the expression 4 x 2 + 0?

Back

The result is 8. First, calculate 4 x 2 = 8, then add 8 + 0 = 8.

Front

What is the role of parentheses in mathematical expressions?

Back

Parentheses indicate which operations should be performed first in an expression. For example, in (2 + 3) x 4, you would first calculate 2 + 3 = 5, then multiply by 4 to get 20.

Front

What happens if you do not follow the order of operations?

Back

If you do not follow the order of operations, you may arrive at an incorrect answer. For example, calculating 2 + 3 x 4 without following the order would lead to 20 instead of the correct answer, which is 14.

Front

What is the difference between multiplication and addition in terms of order of operations?

Back

Multiplication is performed before addition in the order of operations. This means that in an expression with both operations, you should calculate the multiplication first.

Front

Can you give an example of an expression that requires the use of parentheses?

Back

Sure! In the expression 3 + 5 x 2, if you want to add 3 and 5 first, you would write it as (3 + 5) x 2, which equals 16 instead of 13.

Front

What is the value of the expression 5 + (2 x 3)?

Back

The value is 11. First, calculate the expression inside the parentheses: 2 x 3 = 6, then add 5 + 6 = 11.
