Addition , subtraction, multiplication and division

What happens when you use decimals instead of integers for these operations?

Thank you

What question are you trying to answer? Will depend on the numbers used.

No numbers involved. That's exactly how the question is worded

Well additions and subtractions will behave in the same way for both integers and decimals but multiplications and divisions will do the opposite, is that what they mean do you think?
eg 2x2 would be 4 ( larger ) but 0.2 x 0.2 would be 0.04 ( smaller )

Your answer is also likely to include a decimal?
That’s a weird question. The only part that I can think the might be aiming at is that multiplying by a number smaller than 1 (eg 0.5) will make your number smaller and dividing by a number small than 1 (eg 0.5) will make your number bigger.
With addition and subtraction you just have to make sure you line up the decimal points properly if you’re doing sums written out by hand. So don’t get 0.5 mixed up with 0.05 kind of thing.

Who is this question aimed at? How is it presented? Are there other questions?

What do they mean by 'what happens...'? Surely decimals are added, subtracted, multiplied or divided just like integers are. But, like @Desperatelywantinganother says, you have to make sure the decimals line up, so you correctly add 10.5 and 1.05 or whatever.

It's not really a maths question in any conventional sense because, even if you don't understand the maths itself, there shouldn't be any ambiguity in what the question is asking.
