Simple math

[SFMLNewGuy]

Hello,

I'm so rusty with math, it has been my downfall learning how to program. I honestly need to take a course again and I have something called Khan to check out.

With that said, I just have a simple question regarding this formula

A + B = ||A||||B||           

Do I add or multiply the magnitude of A and B. I'm having one hell of a time finding clarity to this? I'd assume multiply, but from the examples I see, it looks like you use addition.

Any help, sorry if this is the wrong place to ask. I'm just kind of stuck on this.

EDIT: And if someone could explain why SFML used degrees instead of radians I would appreciate it. Thanks

What is this nonsense?

I know the boolean operator || in programming generally means OR ("if A || B is true do...") so I think this wouldn't compile on a program. I think this forum is meant for questions related to SFML and such, so I don't think you'll get much help here. Maybe try reddit? Sorry bud.

Hi,
There is no operator to compute the magnitude of a Vector. Vertical bars '|'  have a different meaning in maths and in programming.

Hello.

A + B = ||A||||B||           

I expect this formula is:
A + B = ||A|| ||B||
and I would read it as:
A plus B is the same as the product of the magnitude of A and the magnitude of B.

although what that means in context would be down to what the formula is for.
