I think a PC is a more apt comparison. Yes we learnt them in computer class but they weren't in the Math classroom. Hell learning software engineering I didn't use my laptop at all during lectures.
And applied math on a PC would be great, but we barely have applied math on a calculator.
And kids love calculators: only digital numbers are numbers. 2/3 is cleary not a number to anyone below 20 years of age, that is two numbers, we have to write .6666666\dash_over{6} down as a solution instead.
I'm not sure how to interpret your last statement, but that seems like a problem worth correcting if true? They're going to need to understand fractions to do any math more advanced than elementary school level.
