    By itself like that, I am more inclined to go with 'a divides b.'

    according to course im taking \(b|a\) means \(a\) is divisible by \(b\) which is values of either true, or false

    I kinda made up that word, "typology," though; apparently that already means something else. What I meant was "type-setting."

    Zero is divisible by everything, but I wouldn't say that zero is *divided* by anything.

    There is a difference between "divides" and "is divisible by."

    i would say , just do a/b if that comes out to be integer , then true, else false

    Being a factor and being a divisor are two different things (but that distinction might not matter in the application you are using).
