hmmm. That is interesting. 14 - 32 = ?

I worked it out like this:

 14

-32

-22

 

4 - 2 = 2

and

10 - 30 = -20

 

So why is the answer -18 not -22? Should I subtract the 2 from the -20? Why would I do that?

I worked it out like this:

-32

-22

 

4 - 2 = 2

and

10 - 30 = -20

 

Then you would have to work out -20 + 2.

And THAT is equal to 18.

 

So I finally figured it out.

It's not like that...

\(\boxed{a-b=-(b-a)}\)

That's because \(\boxed{-(-a)=a}\)

So 14 - 32 = -(32 - 14) 

You do the stuff in the bracket: = -18 :D

32 - 14 is elementary math :)
