How do you read out 2 x (-5)
in the most common, accepted way, in a way a kid in school would?
I know that 2 x 12 reads out "two times twelve", so is it "two times negative five"?
I think I heard "two by twelve", also. Are there two conventional readings? Maybe more?

    Don't be confused with "a 2 x 4" (at least in the US) which describes a piece of wood with a (nominal) cross section of 2" by 4". It is not a multiplication. There are also 2 x 6, 2 x 12 etc. Without the word "multiply, I'd advise against using by:)
