1. 49
   48
2. 47
   53

When you multiply 7 times 7, you get 49. This means that the square root of 49 is also 7.

1. 22
   30
2. 25
   36

When you multiply 5 and 6 together, you get 30. As the hint implied, 20 + 10 is also 30.

1. 1
   10
2. 0
   100

The answer is 0. When you multiply anything by 0, the answer is 0.

1. 11
   21
2. 1
   20

20 is the right answer. When you multiply any number, like 20, 5, or 10 by 1, the answer is still 20, 5, or 10.

1. 33
   23
2. 43
   3

The answer is 33. Another example is 11 times 4 is 44, and 11 times 5 is 55.

1. 10
   100
2. 110
   120

When you multiply 10 and 10 together, you get 100. This means that the square root of 100 is 10.

1. Cannot be computed
   1
2. -1
   0

-1 is the right answer. When you multiply a positive and a negative number together, the answer is always negative.

1. 4
   -4
2. 2
   -2

2 + 2 is 4 and -2 times -2 is also four. When you multiply two negative numbers together, the answer is always positive.

1. 55
   25
2. 125
   75

125 is the right answer. Another way to rewrite this is 5(5)(5) or 25(5).

1. 8
   4
2. 6
   10

6 is the correct answer. Another way to rewrite this is 3(2)(1). 3(2) is 6 and 6(1) is 6.

1. 15

5 is the correct answer. When you multiply a number by .5, you're just cutting that number in half.

1. -23
   23
2. 27
   -27

-27 is the right answer. Look at the problem like this: 3(-3)(3), which is -9(3) which is -27.

1. 6
   4
2. 6.25
   4.75

6 is the correct answer. When you multiply 24 by .25, you're just separating that number into fourths, or quarters. In other words, 6(4) is 24, which is the same thing as 24 times .25.

1. .15
   .75
2. .25
   1

1/4 or .25 is the right answer. When you multiply .50 and .50 together, you get a smaller number, which is .25.

1. 27
   45
2. 55
   50

50 is the right answer. When you multiply a number by 2, you're just doubling that number.

1. 50
   75
2. 25
   5

The answer is 75. When you multiply a decimal by 100, you're just moving that decimal to the right two times.

1. 150
   1500
2. 15
   50

The answer is 150. When you multiply a decimal by 1000, all you have to do is move the decimal over to the right three times, hence .15 becomes 150.

1. 80
   -80
2. 42
   -42

-80 is the right answer. When you multiply three negative numbers together, the answer is always negative.

1. 13
   12
2. 15
   8

The answer is 15. Here's why: the square root of 25 is 5 and the square root of 9 is 3. 5 times 3 is 15.

1. 20
   26
2. 22
   24

The right answer is 24. The square root of 9 is 3, the square root of 16 is 4 and the square root of 4 is 2. 3 times 4 times 2 is 24.

1. -16
   4
2. -4
   16

The correct answer is 4. -√4 is -2, since the square root of 4 is 2, but there is a negative sign in front, so it becomes -2. -2 times -2 is 4.

1. -1
   0
2. 1
   2

The answer is 0. √1 is 1 and √0 is 0, so 1 times 0 is 0.

1. 36
   38
2. 24
   26

36 is the right answer. 2² is 4 and 3² is 9, so 4 times 9 is 36.

1. 29
   27
2. 28
   13

27 is the right answer. 3³ is 27 since it's basically 3(3)(3). 1³ is 1, so 27 times 1 is 27.

1. -75
   125
2. -125
   75

-125 is the right answer. 5² is 25, so 25 times -5 is -125.

1. 38
   -38
2. 32
   -32

If you guessed -32, you're right! √4 is 2 and (2²) is 4, so the problem is just 2 times -4 times 4, which is -32.

1. -5
   5
2. 4
   -4

-5 is correct. Multiplying a number by .25 is just quartering that number, so when you quarter 20, you get 5. But since .25 is negative, it becomes -5.

1. 5
   15
2. 50
   25

The right answer is 5. √100 is 10 and 10 times .50 is 5.

1. 15
   -5
2. 5
   25

The answer is 5. -√25 is -5 because the square root of 25 is 5, but since there is a negative sign in front, it becomes -5. -5 times -1 is 5.

1. 10
   75
2. 50
   5

50 is the right answer. 50% can be rewritten as .50, and .50 times 100 is 50 (it's just half of 100).

1. .060
   .60
2. .0060
   .36

The answer is .60. While the problem looks tricky, just break it down step by step. √36 is 6, since 6 times 6 is 36. 10% can be rewritten as .10, so now the problem is .10 times 6, which is .6. You're just moving the invisible decimal place in front of the 6 to the left once.

1. 30
   10000
2. 1000
   100

1000 is the right answer. 10 times 10 is 100 and 100 times 10 is 1000.

1. 24
   16
2. 60
   -60

-60 is the right answer. When you multiply a positive number and a negative number together, you get a negative number.

1. 35
   50
2. 25
   45

50 is the right answer. 10 times 5 is 50, which means 50/10 is 5 and 50/5 is 10.

1. 17
   777
2. 77
   7

77 is the right answer. 11 times 7 is 77, just like how 6 times 11 is 66 and 5 times 11 is 55.
