I know like 8 % 12 = 8 and stuff like that

OK no problem, let me give you an introduction to the modulus of complex numbers.

Let there be Z (a complex number ) = a + ib So , we have to find the modulus of Z = Z = a+ib It is given by Z = \(\sqrt{x^2+y^2}\)

so let us take the question itself as an example : 78i = \(\sqrt{7^2+8^2}\)= \(\sqrt{49 + 64} = \sqrt{113}\)

i plotted the point 7  8i on an Argand diagram, then used the Pythagorean relation to determine the distance form the origin of the point
