Commands inside textbf
I was working on creating a small table of formulas for my Math class. Since I will be using a lot of vector related stuff I defined and redefined some commands to suit my needs. Below you see my commands
renewcommand{vec}[1]{textbf{#1}} %Vector
newcommand{scalar}[2]{langle vec{#1},vec{#2} rangle} %Scalar
newcommand{crossp}[2]{vec{#1} times vec{#2}} %Crossproduct
The problem is that using the following code results in strange behaviour I do not understand and cannot find any help on.
begin{equation}
V = scalar{u}{crossp{v}{w}}
end{equation}
I have also tried using textbf{...} directly, without using the vec function.
I know that vec is basically obsolete, but I use it so I can see what is bold text and what are vectors when reading my code.
The problem is also not resulting from applying vec twice, as I have also tried simple inserting v times w, which produces the exact same behaviour.
Can anyone explain why this is happening and propose a fix?
Thanks in advance.

The fix is simple: use mathbf and not textbf:
renewcommand{vec}[1]{mathbf{#1}}
Your code produces errors, the first of which is
! Missing $ inserted.
<inserted text>
$
l.10 V = scalar{u}{crossp{v}{w}}
because textbf enters text mode.
Even if that would be solvable you'd get in real trouble with something like the following:
documentclass{article}
usepackage{amsmath}
newtheorem{theorem}{Theorem}
renewcommand{vec}[1]{textbf{#1}} %Vector
begin{document}
A vector $vec{v}$.
begin{theorem}
A vector $vec{v}$.
end{theorem}
end{document}
Do you see the problem? This doesn't happen if you change textbf into mathbf:
