Adding Complex Numbers: (12-3i) + (7+3i)
In mathematics, complex numbers are numbers that can be expressed in the form a + bi, where a and b are real numbers, and i is the imaginary unit, defined as the square root of -1.
To add complex numbers, we simply add the real parts and the imaginary parts separately.
Let's add (12-3i) and (7+3i):
(12 - 3i) + (7 + 3i) = (12 + 7) + (-3 + 3)i
Simplifying the expression, we get:
(12 - 3i) + (7 + 3i) = 19 + 0i = 19
Therefore, the sum of (12-3i) and (7+3i) is 19.
