Question

Abdul solved the following problems and he made some mistakes. Can you find his errors and fix them?

(12-5i)+(10+6i)=23i

Answer 1

When adding complex numbers, we add the real parts and the imaginary parts separately.

Step-by-step explanation:

In the expression (12-5i)+(10+6i), we add the real parts and the imaginary parts separately.

The real parts are 12 and 10, so 12+10=22.

The imaginary parts are -5i and 6i, so -5i+6i=i.

Therefore, the correct result is 22+i.
