75 + (-43) - (-56) -12
75 - 43 + 56 -12 (distribute the signs- adding a negative is the same as subtraction, and subtracting a negative is the same as addition)
32 +56 - 12
88 - 12
76

Peter, here are the steps:
75+(-43) = 75-43=32
32-(-56) = 32+56 (minus a negative is same as plus a positive)
=88
88-12 = 76

75 + (-43) - (-56) - 12 simplify
75 - 43 + 56 - 12 = 76 remember 2 negatives equal a positive.
this goes under the order of operation. An easy way to remember
the order of operation is pemdas: p = parenthesis e = exponents
m = multiplication d = division a = addition s = subtraction. this
is the order you should solve a problem like that.

well you could just do it on a calculator but...
75-43+56-12 = 77
because a '+' by '-' equals '-'
'-' by '-' equals '+'
and '-' just equals '-'
