Texas Instruments TI-35 Handheld Electronic Calculator

This scientific handheld electronic calculator has a relatively thin black plastic case with an array of forty small rectangular black plastic keys (one key is missing on this example). These include ten digit keys, a decimal point key, a change sign key, a total key, and four arithmetic function keys. Further keys are for reciprocals, percentage, off, on/clear, sines, cosines, tangents, enter exponent, common logarithms, natural logarithms, powers, a constant, left parenthesis, and right parenthesis. Keys in the leftmost column may represent two functions. These are factorial or clear statistical register, square or square root, inverse function or second meaning of key, summation or removal of unwanted data points, storage or mean, recall or standard deviation, summation or a different standard deviation, and exchange or pi. The marks indicating the function of keys are on the keyboard above the keys themselves.

Text above the keys reads: TEXAS INSTRUMENTS TI-35 (/) Constant Memory. Behind the keyboard is an LCD display that shows eight-digit positive and negative numbers or, in scientific notation, a five-digit mantissa and two-digit exponent.

The calculator has a compartment for two very small batteries. Text on the back reads in part: TEXAS INSTRUMENTS (/) electronic calculator. It also gives the serial number 3607829 and a date mark ATA5080. It also reads: ASSEMBLED IN USA.

The calculator comes in a black plastic jacket. It is part of the Slimline series of Texas Instruments calculators that feature LCD displays.
