Question

A is a positive and B is a negative rational number. which operator ( +,-,*,\ between them will always result in a positive number ? give reason for your answer​

Answer 1

For getting a positive rational number for A and B, we cannot use (×) or (÷)

Then, we can use (+) only if A>B. e.g. 7+(-6) = 1; 5 +(-2) = 3 etc.

And also we can use (-) only if the negative number i.e. B is to be subtracted from A. e.g. 4 -(-3) = 7 etc.

HOPE THIS COULD HELP!!!
