    Simple math questions

    Hi there!

    I have some simple questions on elementary math:
    What's the most usual way to ask about additive and multiplicative calculations,
    such as

    1a) How much is two plus three?
    1b) How many is two plus three?
    1c) How does it make two and three?
    1d) Two and three are ... ?
    1e) Two plus three gives ... ?

    2a) How much/many is/are three minus two?
    2b) What is three minus two ?

    3a) What is three times two?

    Are any of the sentences above correct? Which are the most common ones on American English? What about the answers?

    1. what is the additive inverse of 3? -3 ans.

    2. what is the multiplicative inverse of 4? 1/4 ans.

    Re: Simple math questions

    1a) How much is two plus three? (Two plus three is/equals five.)
    1b) How many is two plus three?
    1c) How does it make two and three?
    1d) Two and three are ... ?
    1e) Two plus three gives ... ?

    2a) How much/many is/are three minus two? (Three minus two is/equals one.)
    2b) What is three minus two? (Same answer as 2a.)

    3a) What is three times two? (Three times two is/equals six.)

    If it's not lined out, it's fairly standard for American English.

    Re: Simple math questions

    Mamen: Thanks for your somewhat more technical contribution.

    Dragn: Thank you very much for bringing us some of the American
    Way regarding those elementary calculation, that was exactly my
    point.

    Just to confirm Dragn, so it is also correct to say
    "What is two plus three?" (similar to "what is three times two") ?
    Is it common?

    At first I had questioned only about American English, but I would like
    to know also if there are differences on this subject, regarding elementary
    plus/minus/times calculations, on other English standards.

    Yes, that is what I meant. It's fine.

    Re: Simple math questions

    Hi fellows!

    How is the boundary math symbol pronounced?
    It is the same symbol used for partial derivative in mathematics.
    I think it comes from the cyrilic letter for "d".

    I heard it is pronounced as "der" or "dow", is it so?

    Re: Simple math questions

    Chiefly British:

    Here's a multiplication (146 x 281) together with all its steps, in words that a Brit might have used as he/she was working it out on paper before the days of pocket calculators.

    00146
    x0281
    ------
    29200
    11680
    00146
    ------
    41026

    A hundred and forty-six times two hundred and eighty-one.

    beginning: Put down two noughts. Two sixes are twelve; put down two and carry one; two fours are eight and one are nine; two ones are two.

    next line: Put down one nought. Eight sixes are forty-eight; put down eight and carry four; eight fours are thirty-two and four is thirty-six; put down six and carry three; eight ones are eight and three is eleven.

    next line: One times 146 is 146.

    addition: Six and nought are nought is six; eight and four and nought is twelve; put down two and carry one; six and two are eight and one is nine and one is ten; put down nought and carry one; none and one are ten and one is eleven; put down one and carry one; two and one are three and one are four.

    total: forty-one thousand and twenty-six.

    And he or she would refer to the whole thing as "maths" rather than "math".

    Thanks a lot marciobarbalho! I wonder if there would be remarkable differences regarding AmE.
