Answer to Q85

Is a - b - c = a - (b - c)?

This question generates from a mistake I made while in a rush to do the calculation 18 - 3 - 2. Immediately I saw the question, I (been in a hurray and not thinking clearly) did a stupid 3 - 2 = 1; 18 - 1 = 17

Immediately I saw my answer, my instinct told me something is wrong with it. then I saw my mistake!

What I should have done was -3-2 = -5; 18 - 5 = 13!

a - b - c can not be equals to a - (b - c)

Expanding a - (b - c) will give you a -b -(-c) = a - b + c
That was why I got 17 earlier (18 - 3 + 2)

Answer: False
