Question

write the expression as a complex in standard form (1+i)+(5+2i)=

Answer 1

6+3i

Answer 2

3i+6 I mean. -.-

Answer 3

I think its real + imaginary.

6 + 3i was correct :)

Answer 4

i is treated like any other variable. the only exception is that i^2 = -1.

Answer 5

ok

Answer 6

write the expression as a complex number in standard form (1+i)(-1+i)

Answer 7

1(-1) +1(i) -1(i) + i(i)

-1 + i^2

-1 +(-1) = -2

-2 + 0i or simply exclude the "imaginary" part:
-2
