That means, the SIZE of the number. Complex number with Real and Imaginary components, which is a point in two dimensions.
You find how far away it is from the origin. This works like a right triangle.
4 in the Real direction, +2 in the Imaginary direction.

abs%284%2B2i%29=sqrt%284%5E2%2B2%5E2%29=sqrt%2820%29=highlight%282%2Asqrt%285%29%29

Pythagorean Theorem.
