Using facts to solve problems means understanding that subtraction is the inverse of addition, and vise versa. Therefore, if you know that 6 + 4 = 10, you could find the missing number in 10 - ? = 4 by using the same numbers.

This quiz will help your child to solve missing number problems by using number facts known to them.

Can you find the missing number?

1 .
You could use 45 + 55 = 100 to help you solve:
100 - 5
40 + 500
100 - 20
100 - 55
If 45 + 55 = 100, you could solve 100 - 55 = 45
2 .
What is the missing number:
20 - ? = 7
70
30
3
13
If 7 + 13 = 20, then 20 - 13 = 7
3 .
Which number is missing:
100 - ? = 20
12
18
20
80
20 + 80 = 100 so 100 - 80 = 20
4 .
What is the missing number:
12 + ? = 20
18
8
22
12
12 + 8 is a number pair, or bond, to 20
5 .
If 95 + 5 = 100 is true, which of the following is not true?
95 + 95 = 100
5 + 95 = 100
100 - 95 = 5
100 - 5 = 95
The numbers in each calculation should always be 5, 95 and 100
6 .
Which fact would help you solve:
10 - ? = 4
8 + 2 = 10
10 + 4 = 14
4 + 6 = 10
10 + 6 = 16
If 4 + 6 = 10, then 10 - 6 = 4
7 .
If 16 + 84 = 100 is true, which of the following is not true?
84 + 16 = 100
100 - 84 = 16
16 + 16 = 84
100 - 16 = 84
16 + 16 = 32, not 100
8 .
You could use 100 - 25 = 75 to help you solve:
25 + 75
75 - 25
75 - 100
25 - 100
If you know that 100 - 25 = 75, then you could solve 25 + 75 = 100
9 .
If 15 + 85 = 100 is true, which of the following is not true?
100 - 15 = 85
100 - 85 = 100
100 - 85 = 15
85 + 15 = 100
100 - 85 = 15, not 100
10 .
Which number is missing:
? + 5 = 20
50
15
5
20
20 - 5 = 15, so 15 + 5 = 20
