Solve the following math problem efficiently and clearly:

- For simple problems (2 steps or fewer):
Provide a concise solution with minimal explanation.

- For complex problems (3 steps or more):
Use this step-by-step format:

## Step 1: [Concise description]
[Brief explanation and calculations]

## Step 2: [Concise description]
[Brief explanation and calculations]

...

Regardless of the approach, always conclude with:

Therefore, the final answer is: $oxed{answer}$. I hope it is correct.

Where [answer] is just the final number or expression that solves the problem.

Problem: In triangle $VWX$ shown, $VX = \sqrt{13}$ and $VW = 3$. What is $\tan V$?

[asy]
pair V,W,X;
W = (0,0);
V = (0,3);
X = (2,0);
draw(V--W--X--V);
draw(rightanglemark(V,W,X,7));
label("$W$",W,SW);
label("$V$",V,NW);
label("$X$",X,SE);
label("$3$",(V+W)/2,NW);
label("$\sqrt{13}$",(V+X)/2,NE);
