Question

If p=1 and q=4, evaluate the following expression:4q−p/p+q​

Answer 1

19

Explanation:

This was done the normal way of multiplying and dividing first:

If p=1 and q=4, evaluate the following expression:

4q − p/p + q​ = ?

4(4) - 1/1 + 4 = 16 - 1 + 4 = 19

If you wanted to do the addition and subtraction first, the equation would have been:

(4q - p)/(p + q) = ?

(4(4) - 1)/(1 + 4) = 15/5 = 3

With the parentheses, the order of operations is done in the parentheses first.
