Another way to write two parts of a complex number is Re\mathrm{Re}Re and Im\mathrm{Im}Im so that Re(z)=a\mathrm{Re}(z)=aRe(z)=a, and Im(z)=b\mathrm{Im}(z)=bIm(z)=b. This time, the real part can be written as Re(A * B) = x * m y * n, and the imaginary part as Im(A * B) = x * n + y * m. Remember that complex number calculators use a negative sign in the real part because, at some point, we are faced with the product of two numbers i * i, which by definition is -1. If we capture the data we may see it listed as Real and Imaginary. In other words, it is a complex number which is written as the product of the real number and the imaginary unit i.
