Begin by substituting $14$ $14$ in for $p$ $p$ because that is its value:

$\frac{14}{2} - 5$ $14/2-5$

Follow the order of operations:

P.E.M.D.A.S

Parenthesis, Exponents, Multiply, Divide, Add, Subtract

Skip the first 3 steps (P.E.M.) because that doesn't apply in this problem

So, the first step in this problem is to Divide

*Remember that every fraction is just division

$\frac{14}{2} = 7$ $14/2=7$

So, the problem now looks like:

$7 - 5$ $7-5$

The next step would be to Add, but that doesn't apply, so subtract

$7 - 5 = 2$ $7-5=2$
