\frac{\mathrm{d}}{\mathrm{d}x}(82-3x)
Add 60 and 22 to get 82.
-3x^{1-1}
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 ax^{n} is nax^{n-1}.
-3x^{0}
Subtract 1 from 1.
-3
For any term t except 0, t^{0}=1.
82-3x
Add 60 and 22 to get 82.
