PEMDAS

What does PEMDAS stand for?

• Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)

• Parentheses, Exponents, Multiplication, Addition, Division, Subtraction

• Parentheses, Exponents, Division, Multiplication, Addition, Subtraction

• Parentheses, Exponents, Addition, Division, Multiplication, Subtraction

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

• Solve any expressions inside Parentheses.

• Multiply any numbers in the expression.

• Add or subtract numbers from left to right.

• Evaluate exponents in the expression.

What is the result of the expression 20 ÷ 4 x 5?

• 20

• 25

• 15

• 30

How do you handle Multiplication and Division in PEMDAS?

• Multiplication is done before Division regardless of their order in the expression.

• Multiplication and Division are handled from left to right, depending on which comes first in the expression.

• Division is always done before Multiplication in PEMDAS rules.

• Multiplication and Division are ignored in PEMDAS.

What is the result of the expression (8 x 8) + 12 x 2?

• 64

• 88

• 76

• 80

Can you give an example of a problem that involves both multiplication and division?

• 15 ÷ 3 x 4

• 20 ÷ 4 x 5

• 30 ÷ 6 x 2

• 10 ÷ 2 x 3

What is the correct order of operations in PEMDAS?

• Parentheses, Exponents, Addition and Subtraction (from left to right), Multiplication and Division (from left to right)

• Parentheses, Multiplication and Division (from left to right), Exponents, Addition and Subtraction (from left to right)

• Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)

• Exponents, Parentheses, Addition and Subtraction (from left to right), Multiplication and Division (from left to right)

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

• You will always get the correct answer.

• You may arrive at an incorrect answer.

• It will not affect the outcome of the calculation.

• The calculation will take longer to complete.

True or False: Multiplication always comes before addition in PEMDAS.

• True, but both operations are performed from left to right.

• False, addition always comes before multiplication.

• Multiplication and addition are performed simultaneously.

• Multiplication comes after addition in PEMDAS.

What is an example of an expression that requires the use of PEMDAS?

• 3 + (2 x 5) - 4

• (8 - 3) + 2 x 5

• 5 + 3 x (2 - 1)

• (6 + 2) / 2 + 1
