To the HP 32s was added a second shift key, and this allowed quicker access to many functions that were previously buried in menus. The 32sII also added fraction support, accessed by pressing the decimal point key twice. The 32sII also updated the solver to algebraic entry, versus the original RPN entry on the 32s. The original color scheme (orange left-shift and blue right-shift keys) was similar to that of the HP 32s and HP 48SX, but in 1999 HP changed the color scheme to a dark green left-shift and lilac right-shift.

The quick availability of functions on the HP 32sII led it to become the calculator of choice for the Texas UIL calculator competitions.
