Like the HP-32S except for additional support for algebraic math and fractions. Fractions are entered by pressing the decimal key a second time. For example, to enter one and a quarter, the user would press "1.1.4". This model also added a second shift key, simplifying menus at the expense of a more cluttered keypad design. Introduced in 1991 and sold through 2002.
