Hello all,(adsbygoogle = window.adsbygoogle || []).push({});

My first post here and sorry it is not very scholarly. lol

I am currently taking Algebra 2 and am completely lost as how to find the answers to simple equations and expressions such as the ones below. Can anybody help me out or if you own a TI-89 Calc and know how to perform these operations, please let me know! I will need to do it by hand but if I can do it on the Calc I can learn better with having the answer before hand and such. Well anyway, here are the examples.

1. (4 - i) + (3 + 2i) change to standard form

2. 5i(-2 + i)

Thanks everybody!^^
