Those two numbers can't be directly added as long as they're in
radical form. The only way to add them is to find both square roots,
and then add those.
Another twist is the fact that every number has two square roots ...
one positive and the other negative. So there are four possible sums
of (√3 + √4).
√3 = + or - 1.732051 (rounded)
√4 = + or - 2 (exactly)
The four sums are:
(+1.73205) + (+2) = 3.732 (rounded)
(+1.73205) + (-2) = - 0.268 (rounded)
(-1.73205) + (+2) = + 0.268 (rounded)
(-1.73205) + (-2) = - 3.732 (rounded)
