ok guys a couple more if you dont mind :D (this is a math help forum so im sure most you wont mind ;D)

Directions - Simplify the following problems

24. (3-5i) + (4+6i) = 7+i

25. (2-2i) - (2+2i) = -4i

26. (-6i)(-4i) = 24i^2

I have a few more that need to be checked but they have radical signs in them and I dont know how to type it out on the keyboard =/
