    to do sums

    When someone says he likes arithmetic and likes to do sums, does "to do sums" mean like multiplication, division, subtraction and addition or only addition?
    thank you

    Re: to do sums

    It's usually only children who talk about doing sums. They mean all four of those operations – not just addition.

    Adults say they like maths (AE math).

    Thank you, but what do i call these:


    2x2=4
    4/2=2
    2+2=4
    4-2=2

    are these still called sums, even if it's an adult speaking?

    Re: to do sums

    I would only call addition "sums."

    Re: to do sums

    I am not a teacher.

    And I wouldn't call any of it maths. It's arithmetic.

    These are arithmetical sums/problems/operations.

    Arithmetic is the branch of mathematics that deals with this sort of simple manipulation of numbers.

    Re: to do sums

    I'm with Dave. I think we understand that "arithmetic" is a subset of "math(s)" but I would never say "I like arithmetic" or "I'm struggling with the arithmetic" or anything like that. I'd just say "math." Must be the American perspective.
    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.

    Re: to do sums

    What do you call it when you do the calculation in your head?

    I call it mental arithmetic.

    Re: to do sums

    Just last night, I said to someone (referring to my husband), "He can do math in his head faster than anyone I know."

    I do agree that "mental arithmetic" does collocate, but on its own, I don't use the word much, if at all.
