Question

If d = 8, what is the value of the expression 4+d/2 ?

Answer 1

First put your numbers in the right places. 4+8/2. Do your steps of P-E-M-D-A-S. There are no parentheses. There are no exponents either. There is not a multiplication problem. but there is a division problem= 8/2. So 8 divided by 2 is 4. The equation looks like this now: 4+4. Add them together and get 8. You don't have anything to subtract. Your answer will be 8.

Answer 2

Question: If d=8, what is the value of the expression
`4+\frac{d}2` ?

Just substitute in 8 for d and evaluate.


`4+\fracd2=4+\frac82=4+4=\boxed8`

If the question was instead d=8 for the expression
`\frac{4+d}2`, your answer would look like this:


`\frac{4+d}2=\frac{4+8}2=\frac{12}2=\boxed6`
