calculator

Calculators {calculator}| {electronic calculator} can be for adding, subtracting, multiplying, dividing, and other algorithms. Electronic calculators store binary numbers in diodes in electric circuits. Arithmetic operations select different circuits to process signals.

Calculators use a metal-oxide semiconductor chip with 28 terminals, four for keyboard, eight for display, eleven for scan lines, one for clock, and three for power.

A timing mechanism at 250,000 cycles per second synchronizes input from display and keyboard, using scan lines. Diodes and keyboard functions can only activate if scan line is on.
