Question

IV. Answer the following questions:
11. Verify a - (-b) = a + b for a=25, b =15
12. Find: (i) (-17) x (-29) (ii) (18) - (-3)
13. Solve: 2+ 3/5
14. Find 2/3 of 18
15. Multiply: 5.935 x 1000​

Answer 1

Answer:

11.

a-(-b) = 25-(-15)

on opening brackets sign will change (as having - outside the brackets)

so it becomes

= 25+15

= 40

taking RHS

a+b = 25+15 = 40.

Answer 2

Answer:

11. 25-(-15)=25+15

SO,40

12. 493,21

13. 13/5

14. 12

15. 5935
