9 (3 x 3).

Front

What operation should be performed first in 6 + 2 - (6 + 1)?

Front

In the expression 5 - 3 + 2, what is the error if addition is done first?

Back

The correct order is to subtract first (5 - 3 = 2, then 2 + 2 = 4).

Front

What does the term 'exponents' refer to?

Back

A number that shows how many times to use the base in a multiplication (e.g., 3^2 means 3 x 3).

Front

What is the result of 8 - 2 + 5?

Back

11 (8 - 2 = 6, then 6 + 5 = 11).

Front

What is the value of (3 + 2) x 4?
