Is it true to calculate the discount first and then addd tax?
Or to calculate tax first then apply the discount which saves more money?
Interesting question
I'm not sure although I think its usually discount before tax and
when I looked it up, people said it is calculated before tax...
So I think it is discount before tax but Thats just my guess~

It doesn't matter. I have calculated alot of stuff like this and I found out that it doesn't matter.
