(-3)-(4)=(-3)+4=1 Minus times minus equals plus. The reason for this we need not discuss.
Four minus three equals one. (Or, 4 - 3 = 1.)
3/4 - 2 = - 1 1/4 or equals - 5/4
3-e = 4-f f-e = 4-3 f-e = 1
28/100 minus 1 1/3 equals -1 4/75
[(1-4)/9] = [(-3)/9] = -1/3
-7
m = 1

7-3=4
It equals 1
4/9 minus 3/4 equals -11/36
