Question 2.
Fill in the missing numbers to solve these equations.
6 + 7 + 3 = _______________
8 + 1 + ____________ = 18
5 + _________ + 2 = 13
13 – ___________ = 8
12 – _________ = 7
12 – 4 = ___________
Answer:
6 + 7 + 3 = 6 + 10 = 16
By adding 6, 7 and 3 we get 16.

8 + 1 + ____________ = 18
Let the unknown number be x.
8 + 1 + x = 18
9 + x = 18
x = 18 – 9
x = 9
So, the missing number is 9.

5 + _________ + 2 = 13
Let the unknown number be x.
5 + x + 2 = 13
7 + x = 13
x = 13 – 7
x = 6

13 – ___________ = 8
Let the unknown number be x.
13 – x = 8
13 – 8 = x
x = 5

12 – _________ = 7
Let the unknown number be x.
12 – x = 7
12 – 7 = x
x = 5

12 – 4 = ___________
Let the unknown number be x.
12 – 4 = x
x = 8

Question 3.
CHALLENGE Fill in the missing numbers to solve these equations.
40 + 18 + 23 = ____________
60 + 47 + __________ = 126
____________ + 67 + 26 = 131
Answer:
40 + 18 + 23 = ____________
58 + 23 = 81
So, the missing number is 81.

60 + 47 + __________ = 126
Let the missing number be x.
60 + 47 + x = 126
107 + x = 126
x = 126 – 107
x = 19
60 + 47 + 19 = 126

____________ + 67 + 26 = 131
Let the missing number be x.
x + 67 + 26 = 131
x + 93 = 131
x = 131 – 93
x = 38
38 + 67 + 26 = 131

50 – x = 25
50 – 25 = x
x = 25

90 + 170 + 64 = ______________
160 + 64 = 224

30 – 20 + ____________ = 25
30 – 20 + x = 25
10 + x = 25
x = 25 – 10
x = 15

123 + 48 – ____________ = 123 – 5
171 – x = 118
171 – 118 = x
53 = x
123 + 48 – 53 = 123 – 5

____________ + 5 = 21
x + 5 = 21
x = 21 – 5
x = 16
16 + 5 = 21

250 + 48 + 2 = ____________
250 + 50 = 300

350 + 118 + 6 = ______________
