Default integral:

 $\displaystyle\int$ $f(x) dx$

Change the size of the answer blanks
 $\displaystyle\int$ $f(x) dx$

Double integral, with a lower limit that is not an answer blank
 $\displaystyle\int$ $\displaystyle\int$0 $f(x,y) dA$

put the limits of integration after the integral symbol instead of on top (and below) by setting limits=>0:
 $\displaystyle\int$ $\displaystyle\int$ 0 $f(x,y) dA$

Fundamental Theorem of Calculus
 $\displaystyle\int$ $f(x) dx$ = $\Bigg\vert$

Summation where the student has to input the summation variable, and the limits of the sum
 $\displaystyle\sum$ $=$

a sum with answer blanks for the upper and lower limits, and the summation variable is i
 $\displaystyle\sum$i$=$

a sum with answer blanks for the upper and lower limits, and summation variable is not used.
 $\displaystyle\sum$
