13
Simplify: x 2 3 =

14
What is 29? Explanation: To find the answer to x 2 3, you must do the exponent first. 2 3 means 2 x 2 x 2 which equals 8. Then you must do the multiplication, (3 x 8). Then, you must add 5.

15
This is the second step when following the order of operations rules.

16
What is Simplify the exponents?

17
Simplify: 20 – x 2

18
What is 24?

19
Simplify: 36 ÷

20
What is 8?

21
This number goes in the blank to make the equation true: 4 + __ x 5 – 3 = 16

What is 3?

23
Jill wanted to identify two numbers whose product is 15. These are two numbers she could use. A.12 and 3 B.30 and 2 C.20 and 5 D.5 and 3

24
What is D. 5 and 3 ? Explanation: Product is the answer to a multiplication problem.

25
This is the estimated product of 304 and 49.

26
What is 15,000? Explanation: Product means the answer to a multiplication problem. To estimate 304 x 49, you need to change the problem to 300 x 50.

27
I am thinking of two numbers. The sum of the two numbers is 6. The difference of the two numbers is 2. The product of the two numbers is 8. The quotient of the two numbers is 2. Hint: Both numbers are less than 5. These are my two numbers.

28
What are the numbers 4 and 2?

29
There are 74 books that need to be put into boxes. Each box can hold 9 books. This is the number of boxes that will be filled.

30
