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.

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

Back

The first step is to solve any operations inside Parentheses.

Front

How do you handle multiplication and division in PEMDAS?

Back

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

Front

What is the result of the expression 4 x (5 + 8) using PEMDAS?

Back

The result is 52. First, solve the parentheses (5 + 8 = 13), then multiply 4 x 13.

Front

What is the result of the expression 3 x 9 + 7 using PEMDAS?

Back

The result is 34. First, multiply 3 x 9 = 27, then add 7.

Front

What is the result of the expression (15 − 5) ÷ 2 x 7 using PEMDAS?

Back

The result is 35. First, solve the parentheses (15 - 5 = 10), then divide 10 ÷ 2 = 5, and finally multiply 5 x 7.

Front

What is the result of the expression 9 ÷ 3 + 4 × 6 using PEMDAS?

Back

The result is 27. First, divide 9 ÷ 3 = 3, then multiply 4 x 6 = 24, and finally add 3 + 24.

Front

What is the result of the expression 12 + 36 ÷ 4 using PEMDAS?

Back

The result is 21. First, divide 36 ÷ 4 = 9, then add 12 + 9.

Front

What is the importance of using PEMDAS in solving mathematical expressions?

Back

PEMDAS is important because it provides a standard order of operations that ensures consistent and correct results when solving mathematical expressions.
