Deal with the real and imaginary parts separately.
So (a + ib) - (c + id) = (a - c) + i(b - d)
If you can subtract whole numbers you can subtract decimals. Forget about the decimal for a sec and subtract the numbers as if they were whole numbers. 2.5 -1.4 =1.1 hope this helps and if not yahoo usually has good examples.
Here are a few: 0 = 1 x = x + 1 (subtract "x" on each side, and you get the previous one!) x2 = -1 (if you want real numbers; however, it has two solutions in the complex numbers) ln x = -1 (same as above: no solution in the real numbers, but it has a solution in the complex numbers) ln x = 0 (no solution, neither in the real numbers, nor in the complex numbers) 0x = 5
you subtract by lining your numbers and start from the ones place and continue going to the left

Complex numbers are a proper superset of real numbers. That is to say, real numbers are a proper subset of complex numbers.
