Well if I add two integers the result is usually not much bigger in terms of space e.g.
28594564654655 + 56467986465464

but if I add two "surds" I get an expression that takes up at least twice as much space e.g. sqrt(2) + sqrt(3). Also there could be complicated ways to simplify the expressions which would be computationally expensive compared to integers.
