Fractional Display — Two digits are al-
lowed for the numerator and another two
for the denominator. The largest proper
fraction allowed would be 99/99. The cal-
culator will also handle improper fractions
i.e., 24/16. Once an operation takes place,
the improper fraction is divided out and is
reduced to its lowest form. Any fraction may
be entered as above. However, once a
problem is entered and operated upon, the
fraction will be rounded and displayed to the
nearest 1/64.

weak or erratic, replace the battery.*
Your calculator is designed to shut itself off
after about 8-12 minutes of non-use. Note:
