$\large \sum_{a=1}^{10} \sum_{b=a}^{10} \sum_{c=b}^{10}{\left( {a \times b+c} \right)}$

What is the number of terms in the series given above?

Details and Assumptions:

• $$\left({1 \times 1+1}\right)$$ and $$\left({1 \times 1+2}\right)$$ are the $$1^{\textrm{st}}$$ and the $$2^{\textrm{nd}}$$ terms of the series respectively.
