Question

Is a – b a positive number or a negative number? How do you know?

Answer 1

Answer:

A positive number.

Any negative subtracted from a positive will always be positive.

Answer 2

Answer:

a-b will be and will always be a POSITIVE number.

This is because a is positive, and b is negative.

However, when you subtract a negative number, you are actually just adding it.

So, a - (-b) = a+b.

This is why, it will always be positive.
