-10 ofc.
Generally, when you have any arithmetic question on the form a - b in which b > a, yielding a negative answer, you can siplify it by this formula:
a - b = - (b - a)
Ex:
74 - 96 ...Doing this the usual way often reqires using a calc. We try our li'l cheating:
74 - 96 = - (96 -74) = - 22 ...The ruse worked: This can easily be calculated w/o calc
