Mental Maths
1. Study the addition patterns and complete the following table:

Since 3 + 3 = 6 Since 5 + 2 = 7 Since 7 + 8 = 15 Since 9 + 9 = 18

So, 13 + 3 = 16 So, 35 + 2 = 37 So, 27 + 8 = 35 So, 19 + 9 = 28

23 + 3 = 26 45 + 2 = 47 47 + 8 = __ 49 + 9 = __
33 + 3 = 36 55 + 2 = __ 67 + 8 = __ 59 + 9 = __

53 + 3 = 56 75 + 2 = __ 87 + 8 = __ 89 + 9 = __

2. Nine squares have shown in this figure which are arranged
diagonally with number 9 at the centre. Fill in the remaining
squares with numbers from 1 to 8 in such a way that the sum of 9
both the numbers in the squares in each side should be equal to 2

9. One has been done for you. 7
