Discover the Calculator!
A Calculator is used for helping people add, subtract, multiply, and divide numbers quickly.
🔌 How Does a Calculator Work?
When you press a key, a tiny electric signal travels to the calculator's chip. The chip turns every number into a code made only of 1s and 0s, called binary, and does the math with millions of tiny switches in a fraction of a second. Then it lights up the answer on the screen. Many pocket calculators run on a small solar strip above the screen.
