Order of Operations (PEMDAS) Practice - A (RC)

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).

Front

What is the first step in solving the expression: 3 + 4 × 6 - 4?

Back

The first step is multiplication: 4 × 6 = 24.

Front

In the expression 10 - 4 ÷ 1 · 5, which operation do you perform first?

Back

The first operation is division: 4 ÷ 1 = 4.

Front

What is the order of operations in the expression 25 × (3 - 1) + 4^5?

Back

First, perform the operation inside the parentheses: (3 - 1) = 2, then multiplication, then exponentiation.

Front

How do you evaluate the expression 2 - (7 + 41) – 15?

Back

First, evaluate the parentheses: (7 + 41) = 48, then perform the subtractions in order.

Front

What is the first operation in the expression 4 - (16 - 2) ÷ 7?

Back

The first operation is subtraction inside the parentheses: (16 - 2) = 14.

Front

What is the result of the expression 4 - (16 - 2) ÷ 7?

Back

First, calculate (16 - 2) = 14, then 14 ÷ 7 = 2, and finally 4 - 2 = 2.

Front

What is the significance of parentheses in PEMDAS?

Back

Parentheses indicate which operations should be performed first, overriding the standard order of operations.

Front

What is the role of exponents in the order of operations?

Back

Exponents are calculated after parentheses but before multiplication, division, addition, and subtraction.

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.
