Operations with Integers Class 7 Solutions Maths Ganita Prakash Part 2 Chapter 2 Figure it Out (Page 25) Q. Let us try to find a few more pairs of numbers from their sums and differences: (a) Sum = 27, Difference = 9 (b) Sum = 4, Difference = 12 (c) Sum = 0, Difference = 10 (d) Sum = 0, Difference = – 10 (e) Sum = – 7, Difference = – 1 (f) Sum = – 7, Difference = – 13 Solution: (a) Sum = 27, Difference = 9 Therefore, the numbers are 18 and 9. (b) Sum = 4, Difference = 12 Therefore, the numbers are 8 and -4. (c) Sum = 0, Difference = 10 Therefore, the numbers are 5 and -5. (d) Sum = 0, Difference = – 10 Therefore, the numbers are -5 and 5. (e) Sum = – 7, Difference = – 1 Therefore, the numbers are -4 and -3. (f) Sum = – 7, Difference = – 13 Therefore, the numbers are -10 and 3. Figure it Out (Page 31) 1. Using the token interpretation, find the values of: (a) 3 × (– 2) (b) (– 5) × (– 2) (c) (– 4) × (– 1) (d) (– 7) × 3 Solution: (a) 3 × (– 2) Two red tokens 3 times = (–6) So, 3 × (– 2) ...
