Answer 2

To divide or multiply integers, we first perform the operation on them as whole numbers and then we add the 'plus' or 'minus' sign according to these rules:

• A positive integer divided/multiplied by a negative integer or vice versa has a negative quotient/product.
• A negative integer divided/multiplied by a negative integer has a positive quotient/product (minus and minus cancel each other).
• A positive integer divided/multiplied by a positive integer has a positive quotient/product.

The answers-

1. (-3) ÷ (+3)

= (-3) ÷ 3

= (-1)

2. (25) ÷ 5 x (-5)

= 25 ÷ (-25)

= (-1)

3. 0 ÷ (-1)

= 0

4. (-5 + 6) ÷ (-6 + 5)

= 1 ÷ (-1)

= (-1)

5. (-6 + 5 + 4) ÷ (2 - 1)

= 3 ÷  1

= 3

6. (-36) ÷ (12 x 3)

= (-36) ÷ 36

= (-1)

7. (-206) ÷ (206)

= (-206) ÷ 206

= (-1)

8. (-87) ÷ (87)

= (-87) ÷ 87

= -1

9. (+20) ÷ (-4 x 5)

= 20 ÷ (-20)

= (-1)

10. (-4 x 5) ÷ (20)

= (-20) ÷ 20

= (-1)
