Sorry to be rude, but COME ON - any multi-term calculation should be automatically interpreted as calculator input.
This query works
200000*48
("9600000")
This query gives a 5th grade school teacher answer
200000*48/10242
("9375/1024") - literally WHAT? I'd expect a decimal, not a fraction here.
Any reasonable mathematical term (refer to the calculator feature set of, say, G*****), should be interpreted as expected
