subtract: 3+5i-(-4+6i) is the answer 7-i?
To subtract complex numbers, we can distribute the negative sign to each term inside the parentheses:
3 + 5i - (-4 + 6i)
= 3 + 5i + 4 - 6i (applying the negative sign)
Now, let's combine the real and imaginary parts separately:
Real Part: 3 + 4 = 7
Imaginary Part: 5i - 6i = -i
Therefore, the result of subtracting 3 + 5i - (-4 + 6i) is 7 - i, not 7 + i.
