$$1$$

Steps Using Definition of a Derivative

Multiply 0 and 4 to get 0.

$$\frac{\mathrm{d}}{\mathrm{d}a}(a-0a)$$

Anything times zero gives zero.

$$\frac{\mathrm{d}}{\mathrm{d}a}(a-0)$$

Multiply -1 and 0 to get 0.

$$\frac{\mathrm{d}}{\mathrm{d}a}(a+0)$$

Anything plus zero gives itself.

$$\frac{\mathrm{d}}{\mathrm{d}a}(a)$$

The derivative of ax^{n} is nax^{n-1}.

$$a^{1-1}$$

Subtract 1 from 1.

$$a^{0}$$

For any term t except 0, t^{0}=1.

$$1$$
