Calculus integration problem. [HW help]

• It is probably just a cute way of saying $\int x^2 dx$ or $\int 2x dx$ – Prahlad Vaidyanathan Nov 18 '13 at 16:41
• @Prahlad: I’d interpret as $\int x^2\,dx$, but I’d also explain that I was doing so, interpreting juxtaposition as product the product orange segment with orange segment rather than as two orange segments. – Brian M. Scott Nov 18 '13 at 16:44
Hint: Let $x$ be "orange segment".
Looking at the symbolism the only possible solutions is$$\int x.x dx=?$$ $$\int x^2dx=\frac{x^3}{3}=\frac{x.x.x}{1+1+1}$$
