HINT When using the Math menu, or any menu on the HP 39gII,
the categories and items are numbered for your
convenience. For example, ITERATE is the first item
under Loop, which is the eighth category. With the Math
menu open, press
qx
to insert the ITERATE
function in the edit line at the cursor position. If there are
more than 9 items in a category, the letters A, B, C, etc.
