Complex Numbers

First, Review Group Test 5.3
Alg2_Ch5-1_Practice_Test_Sol.pdf
Then, 5.4 Complex Numbers
• Add/Sub (BM 6.1)
• Mult (BM 6.2)
And graphing complex numbers (BM 5.1)
HW: #26 page 277 #29-55 (o)
Reminder: Chapter 5-1 Test on Thursday, 11/10.

In class we got are practice test back and we got a 1 because of someone elses paper was graded, and the wich i am finding easy so far is comples numbers which is 3 + 2i graphing, which is over 3 and up 2 and (-1+2i)+(3+3i)= 2+5i because its -1+3 and 2i+3i and then there is subtraqcting and multiplying comples nubers which i would do but it would take up too much room.

On Friday we got our group tests back and we got a 12, which was still a passing! But I think we could've done better if we actually stopped goofing off and tried the ones we skipped. And then we learned about imaginary numbers (i)=-1 and how to solve problems with them. I think it's pretty easy.

what can I say? I didn't like the test grade but I can practice more this time ^-^
