Worked practice questions
Two debts of ₹9 and ₹13 are combined. As an integer, the total is
- 22
- 4
- −22
- −4
Show answer and solution
Correct answer: C. −22
(−9) + (−13) = −22 because two debts make a larger debt.
Among −4, −18, −27 and −9, which number is the lowest?
- −18
- −9
- −4
- −27
Show answer and solution
Correct answer: D. −27
The negative number with the largest magnitude is the least, so −27 is smallest.
