PEMDAS

Front

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). It is the order of operations used to solve mathematical expressions.

Front

What is the first step in solving an expression using PEMDAS?

Back

The first step is to solve any operations inside Parentheses.

Front

What is the second step in solving an expression using PEMDAS?

Back

The second step is to calculate Exponents.

Front

In the expression 3 + 4 × 2, which operation do you perform first according to PEMDAS?

Back

You perform the multiplication first: 4 × 2 = 8, then add 3 to get 11.

Front

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

Back

The result is 16. First, solve inside the parentheses: 5 + 3 = 8, then multiply by 2.

Front

How do you handle multiplication and division in PEMDAS?

Back

Multiplication and division are performed from left to right as they appear in the expression.

Front

How do you handle addition and subtraction in PEMDAS?

Back

Addition and subtraction are also performed from left to right as they appear in the expression.

Front

What is the value of the expression 12 - 4 + 2?

Back

The value is 10. Perform the operations from left to right: 12 - 4 = 8, then 8 + 2 = 10.

Front

If an expression has both multiplication and addition, which do you solve first?

Back

You solve multiplication first according to PEMDAS.

Front

What is the value of the expression 2 + 3 × (4 - 1)?

Back

The value is 11. First, solve inside the parentheses: 4 - 1 = 3, then multiply: 3 × 3 = 9, and finally add: 2 + 9 = 11.
