I am puzzled by how does one create a question with MathJax in it. I do not know how to use MathJax and I am asking now for help regarding this situation. Thank you.

Simply include the MathJax between dollar signs ($), like so:
blah blah $\sum_{x=0}^{100}(x)$ blah
blah blah $\sum_{x=0}^{100}(x)$ blah
If you want the MathJax to be displayed as its own block, rather than inline, use two dollar signs:
$$\sum_{x=0}^{100}(x)$$
$$\sum_{x=0}^{100}(x)$$
For a comprehensive tutorial, see this post on meta.Mathematics.
