content: This handheld electronic calculator is similar to the earlier Business Analyst, but has a larger number of functions and a different display. It has a gold-colored metal front with plastic back and trim, and an array of forty small rectangular plastic keys. In addition to ten digit keys, a decimal point key, and a change sign key (all light brown), the calculator has a total key and four arithmetic function keys (all in dark brown). The remaining keys are white. One is for on/clear, one is for off, and another, marked "2nd," is pushed to activate the “dual function” indicated on the keyboard above many of the white and dark brown keys. The calculator has a variety of statistical, business, and mathematical functions, and limited memory.
