Correct?

anonymous · Answer

just write i for example 6i, or 7i, etc.

karatechopper · Answer

yeaa!!!

anonymous · Answer

All right, thanks. So now if I need to add it to something, say my number is5 and I need to add three, does it become 8i, or is it 5i + 3?

Lets see some $$\omega,\omega^2,i$$ complex and imaginary numbers.

anonymous · Answer

Eh?

hba · Answer

Now lets talk about then

$$w=\frac{ -1+ i \sqrt{3} }{ 2 }$$

$$w^2=\frac{ -1- i \sqrt{3} }{ 2 }$$

and

$$i=\sqrt{-1}$$

hba · Answer

Let's see how we get into this imaginary world $$\sqrt{4}=2$$

but
$$\sqrt{-4}=2i$$

hba · Answer

Lets talk about adding


$$5i+3\neq8$$

So your'e wrong.

They will stay as they are

You cannot add Real and imaginary number.

Perfect, the last bit more or less makes sense.
