The dashes are actually roman numerals: the symbol for the forth order derivative would be a slanted IV.

Picking up our earlier example; <math>y = 3 x^2+2x</math>, the second derivative with respect to <math>x</math> is  

Continuing our earlier example; <math>y = 3 x^2+2x</math>, the second derivative with respect to <math>x</math> is  

:<math>\frac{d^{2}y}{dx^{2}} = \frac{d}{dx}(6 x+2)=6</math>

:<math>\frac{d^{2}y}{dx^{2}} = \frac{d}{dx}(6 x+2)=6</math>
