1856 - 3967 = -(3967 - 1856)
do the subtraction inside the ( ) , then change the sign
Yeah I'm serious I can't actually subtract lol...
I always use the column method.
Now if I get a problem like this
OK I got answer 3889 but calculator got -2111
this is how I do it.
I first check and make sure that the top numbers are bigger than the bottom if now start borrowing, then subtract. However I always get the wrong answer
How shall I do this?
