ELI5: Can anyone explain this math question to me?

"Ishaan had to read articles 27 through 53 for homework tonight. 

If Ishaan read all of the articles he was assigned, how many articles did he read?"

I can't wrap my head around this problem, my knee-jerk reaction was of course to subtract 27 from 53 which gives me 26 but the answer is 27. I just can't understand why, shouldn't this be the right way to think about this?

when just subtracting 27 from 53 you're fiding the difference in the number, but you're not taking in to account the starting point, #27, which was read as well.
