INTEGERS A4


Evaluate -100 – 100.

Solution

I have borrowed 100sh on Monday. Again I borrow 100sh on Tuesday. The total money I am required to pay will be a total of 100 and 100. Because it is a debt, the sign will remain to be negative.

Hence -100 – 100= -200



TRY THIS…………..


Evaluate -200 – 300.
