Can you do it another way? Show how.
37 + 21 = 30 + 7 + 20 + 1
Ans. 37 + 21 = 30 + 7 + 20 + 1
= 50 + 7 + 1
= 50 + 8 = 58
73 + 24 = 70 + 3 + 20 + 4
Ans. 73 + 24 = 70 + 3 + 20 + 4
= 90 + 3 + 4
= 90 + 7 = 97
56 + 21 = 50 + 6 + 20 + 1
Ans. 56 + 21 = 50 + 6 + 20 +1
= 70 + 6 + 1
= 70 + 7 = 77
Now work out the steps in your mind. Write the answers directly in the boxes.

Puzzle
Can you solve this puzzle? Write the numbers 1,2, 3, 4,5, 6 in the circles, so that the sum of the numbers on each side of the figure is 12.
Ans.
Upper train have
= (19 – 5) + (6 – 15) + (7 – 3) + (6 – 10) + (4 – 20) + (1 – 7) + (5 – 4)
= 14 – 9 + 4 – 4 – 16 – 6 + 1
= 19 – 35 = -16
Lower train have
= (17 – 20) + (3 – 19) + (9 + 12) + (9 – 20)
= -3 – 16 + 21 – 11
= -30 + 21 = -30 + 21 = -9
