To solve the problem step by step, follow these instructions:

Step 1: Replace the variable p in the expression p-12 with the given value, which is 22. This will give you an expression that can be evaluated.

Step 2: Substitute the value of p into the expression. So, in this case, replace p with 22.

The expression p-12 becomes: 22-12.

Step 3: Perform the operation of subtraction to get the final answer. In this case, evaluate 22-12.

22-12 = 10.

Therefore, when p is equal to 22, the expression p-12 evaluates to 10.
