TI-83 Plus Operating the TI-83 Plus Silver Edition 14
Most TI-83 Plus functions and operations are symbols comprising
several characters. You must enter the symbol from the keyboard or a
menu; do not spell it out. For example, to calculate the log of 45, you
must press « 45. Do not enter the letters L, O, and G. If you enter LOG,
the TI-83 Plus interprets the entry as implied multiplication of the
variables L, O, and G.
Calculate 3.76 ÷ (L7.9 + ‡5) + 2 log 45.
