a and b are negative numbers.
Therefore, a + b is...?
To answer the question, we need to remember that when there is a sequence of minus and plus or plus and minus, the result will be minus.
In other words, (-)+ is actually -.
Let's demonstrate with an example:
Let's say a is -1
and b is -2
(-1)+(-2)=-3
And the result is negative!
Let's try to switch between the numbers, and say that a is -2
and b is -1
(-2)+(-1)=-3
The result is still negative!
Therefore we can conclude that adding two negative numbers results in a negative number.
