Do you mean actually vocalizing "WTF", or just saying "What the fuck"?

>unironically uses the term cross-multiply
But "Cartesian Product" is an ugly term that tells you nothing about what you're actually doing. And don't tell me "cross multiply is wrong, you can only use cross product." Product is the result, multiplication is the action.

"You can get Q by cross-multiplying N with itself." What's wrong with this? How would YOU veribify it?

Not sure about OP, but in local (not english, using direct translation) high schools "cross multiply" means multiplying the equation a/b=c/d by bd.

The people OP refers to use the term as a verb for the above process.

I'm American, and cross-multiply means the same thing in our high schools.

>>9148302
Only in america would they make up a stupid acronym instead of just teaching the distributive law.
