\frac{\mathrm{d}}{\mathrm{d}n}(244-n^{2})
Add 100 and 144 to get 244.
2\left(-1\right)n^{2-1}
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}.
-2n^{2-1}
Multiply 2 times -1.
-2n^{1}
Subtract 1 from 2.
-2n
For any term t, t^{1}=t.
244-n^{2}
Add 100 and 144 to get 244.
