Worked practice questions
Add the product of −5 and −5 to the product of −5 and 5. The total is
- 0
- −25
- −50
- 25
Show answer and solution
Correct answer: A. 0
The first product is 25 and the second is −25, so they cancel to 0.
A shop earns −6 rupees on each of 23 items of type X and −4 rupees on each of 23 items of type Y. The total in rupees is
- −230
- −23
- −10
- 230
Show answer and solution
Correct answer: A. −230
Taking 23 out gives 23 × (−10) = −230.
