Writing in x + iy (1 Viewer)

Will you lose a mark if you write an imaginary with 0 imaginary part as just the real part? I might have made that mistake in my first test, so I just wanna kind of know...

If imaginary part = 0, then number is real (a real number is still a complex number), so you should be OK. 7 = 7 + 0i (but we don't usually write it like this)

@Drongoski oh ok! Thank you for reassuring!

Bear in mind, though, if is purely real but and are complex numbers, it does not follow that and that the number is .

@CM_Tutor yes I agree - it was just that I got a complex number that was purely real when simplified and I wrote the real part and forgot to write 0i as I thought that it was not needed.
