    Angry Do your math

    I have very frequently heard the phrase "do your math" or "If you do your math correctly ..........", etc., but I have not found this phrase/idiom in any of the dictionaries. Is it a standard phrase; can I use it without fear of conveying wrong meaning.

    Re: Do your math

    The phrase you should be looking for is do the math(s) (the 's' is used in BE).

    Re: Do your math

    Does this idiom mean "figure out"?
    Please, correct all my mistakes. I should know English perfectly and if you show me my mistakes I will achieve my dream a little bit faster. A lot of thanks.

    Re: Do your math

    My Oxford dictionary reads "to think carefully about something before doing it...".

    Re: Do your math

    I'd say it's more literal than figurative.

    For example, if you're considering two houses and one has a lower selling price, you might say it's cheaper. But then you look at local taxes, whether there is a neighborhood association fee, how much you might have to pay for snow plowing service each winter, or lawn care costs (even if you do it yourself), and you might find that one house is actually a lot more expensive. We have to do the math to see which one is a better deal.
    I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.

    There are literal and figurative uses.

    Re: Do your math

    The literal one is "do the calculation", correct?

    In this expression, I hear the math being used a lot in BrE, though in other cases it's still maths.

    I agree. We appear to have adopted the phrase in its entirety from AmE. I have never heard anyone say "Do the maths". I have only heard the original version "[You] do the math", even from BrE speakers.
    Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
