twenty negative six plus eight i plus quantity for monies

00:09

to act if i is where were negative one what's

00:13

the sum of the complex numbers above our we're going

00:15

try to add these things well let's think about it

00:18

here This problem can be broken into two smaller problems

00:22

Teo you know make things easier that's because complex numbers

00:25

self segregate the rial number parts pair off together while

00:30

the imaginary parts well do their own thing elsewhere It's

00:33

like another dimension So here it's pretty easy You got

00:36

negative six plus four right there that's negative to you

00:38

had to graduate third grade to get that one Then

00:41

we have eight i plus the quantity negative to ii

00:45

and that's just six i so negative two plus six

00:48

i you know that's the sum of those two complex

00:50

numbers So it seems like this might not be much

00:52

different from working with terms that have regular variables That's 00:00:56.089 --> [endTime] it So this is kind of a gimme
