Subtracts A from B

Question

This is quite an embarrassing question, but what does it mean subtracting A from B?

I got a bit confused and I wouldn't err all the exercise because of this little confusion.

If you are subtracting a from b, then you are taking away a from b, or mathematically subtracting a is the same as adding the opposite of a, ie b + (-a) = b - a. — user 726941, Sep 18 '14 at 20:36

You are correct (Both linguistically and mathematically)

We start with B and remove A

"Subtract A from B" means "From B, subtract A", which equals "B - A".

It should be B-A because you're taking A away from B.
