1. The problem statement, all variables and given/known data
so we have from 27... 63 we want ot calcul how much numbers in there
i was looking in the book and saw 63 -27 + 1 , now this might sound very simple but i got confused why do we add the"1" please explain..
PS:this is astupid uestion i know but it's weird it confused me ..


2. Relevant equations



3. The attempt at a solution
63-27

Not a calculus question, should be in Precalc.

OK, how many numbers from 1 to 5 (including both the starting and ending numbers)?

Is it just 5 - 1? Or is it 5 - 1 PLUS 1?

Same principle when you count from 27 to 63. If you don't add the 1, you're neglecting the starting number.
