Maybe in a rigorous mathematical sense that's true but for most people rational numbers as fractions OR fixed point decimal makes enough sense, and the jump to real numbers is just: more decimal places? I might have to round. You don't even really need algebra first just arithmetic. The jump to complex numbers suddenly introduces a whole bunch of things: letters AND numbers? i*i = -1? Thinking in 2 dimensions and rotations?
