Step 1
We group like terms and work out the final value for each group.
Consider 7y
This is the only term in y so there is no work to be done on it!
Step 2
Consider the integer values of 16 and 8
When grouped we have: +16 and -8. Notice that their signs follow them!
As a whole this is:

16 - 8

which after the subtraction becomes

+ 8

Step 3
Putting at all together we have:

7 y + 8

Step 1

16 + 7 y - 8

Subtract 8 from 16 to get 8.

\frac{d}{d y} (8 + 7 y)

The derivative of a polynomial is the sum of the derivatives of its terms. The derivative of a constant term is 0. The derivative of

a x^{n}

n a x^{n - 1}

7 y^{1 - 1}

Subtract 1 from 1.

7 y^{0}

For any term t except 0,

t^{0} = 1

7 \times 1

For any term t,

t \times 1 = t

and

1 t = t
