Math Don't Make No Sense

How do two Negatives make a Positive?

Here is the problem

-23 - (-41)


the answer is 18.


How can that be answer. The rule doesnt make any sense.

Double negatives make a positive.

You're essentially adding 41 to - 23 (or subtracting 23 from 41).

You're gonna love partial differentials.

Because the difference between the real numbers -23 and -41 on the number line is 18

This is arithmetic. This isn't i or anything. So it still makes sense on a concrete level if you just perceive it from a certain point of view.

Treat it like a balance sheet. You have two charges. Both are costs in the red. One is 23 dollars. One is 41 dollars. This puts you $64 in the red. Except the double negative rule indicates that you have a reversal on the charge from the bank for the second figure. Suddenly you have injected $41 back into your account.

So the sum comes out to $18 in the green.

This guy can't do simple.math, you think he has 64 dollars?

Well could be a trust fund guy

Something tells me you aren't exactly kicking English grammar's ass, either ...

They are the ones who charged your account. By reversing the charge you suddenly get the money credited back to your account.

I inferred from your OP that you are trolling, but there really are a surprising amount of kids who struggled with these concepts when I was in school.

Conceptually, Madmick explains it well.

My algebra teacher taught us to just multiply the signs. Neg X neg = Pos, neg X pos or vice verse = neg. For example 10 - (-6) is like 10 + 6. 10 + (-3) is like 10 - 3. 10 - (+3) is like 10 - 3, etc.
