1. Fill in the missing numbers. You can rewrite each question vertically in your copy if it helps you work out the answer.
a) 25 + d) 18 + g) 66 + j) 22 +
= 36 = 24 = 83 = 65
b) 20 + e) 9 + h) 88 + k) 17 +
= 29 = 28
= 100 = 53
c) 37 + f) 72 + i) 49 + l) 34 +
= 45 = 85 = 78 = 92
2. Can you complete the following number sentences using subtraction? Use the boxes to rewrite the sentence vertically. The first one has been done for you.
a) 265 + = 296 296
– 265 031
c) 578 + = 874 d) 1024 + = 1687 b) 398 + = 489
e) 2548 +
= 3875
f)
+ 389 = 1542
g)
+ 4254 = 8789
h) 3125 +
