_Any_ calculator that isn't a piece of crap will follow the standard precedence rules.
Those rules _must_ be obeyed otherwise the real numbers that everyone loves so much
would not even form a field [this will probably not mean anything to you but...]

If you want 1*2+5*50 to be equal to 350 then enter is as (1*2+5)*50=7*50=350

AFAIK, a $5 calculator will follow precedence..

I hope you realize your error by now..
