whenever we see a variable and number next to each other, we multiply. The value of p is 3 so -2 x 3 is -6. (Remember a negative times a negative is a positive, a positive times a positive is positive, and a negative times a positive is a negative). Then we add -6 + 16 which is 10. Or we could do this: 16 - 6 is 10, which ever's numbers is bigger, the answer will have that number's sign. So since 16 is the bigger number and since 16 is positive, the answer, 10, will be positve.
