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 an expression using PEMDAS?

Back

The first step is to solve any operations inside Parentheses.

Front

How do you handle Exponents in PEMDAS?

Back

Exponents are calculated after parentheses and before multiplication and division.

Front

In the expression 8 + 2 × 5, which operation is performed first according to PEMDAS?

Back

Multiplication is performed first, so 2 × 5 = 10, then add 8 to get 18.

Front

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

Back

The result is 16, calculated as (3 + 5) = 8, then 8 × 2 = 16.

Front

In the expression 12 ÷ 2 × 3, what is the final result?

Back

The final result is 18, calculated as 12 ÷ 2 = 6, then 6 × 3 = 18.

Front

What is the second operation performed in the expression 44 ÷ 2 × (3 - 1)?

Back

The second operation is division (44 ÷ 2).

Front

How do you simplify the expression 40 - 2^4 + 8?

Back

First, calculate 2^4 = 16, then 40 - 16 + 8 = 32.

Front

What is the value of -2 ⋅ (3 + 8 ÷ 4)^2?

Back

The value is -50, calculated as 8 ÷ 4 = 2, then (3 + 2)^2 = 25, and -2 × 25 = -50.

Front

What is the result of the expression 12 ÷ 2 x 3 + (4^3 - 12)?

Back

The result is 70, calculated as follows: 12 ÷ 2 = 6, 6 × 3 = 18, 4^3 = 64, 64 - 12 = 52, then 18 + 52 = 70.
