Dear all

I am new to using Mathematical tools in Moodle. I want to create the quiz with mathematical equations . I enabled TeX notation and and Algebra notion in filters with eyes open. When i typed very simple equation which was delimted by double 'at the rate of' operator in the html editor , it showed the same. It has not been converted into image which needs to be done to show the equation. I tried my best by reading moodle forum to sort it out. So can anyone please help me to write algebraic equation in Moodle?

Thanks in advance.
