Numeric Keypads: 5 Fast Facts

Fact #1. The numeric keypad's introduction into modern computing is a blend of two devices' historical stories: the keyboard and the calculator. The keyboard has its roots in typing, and specifically, the typewriter. The typewriter is said to have been invented as early as the year 1714. The first known working machine was created in 1808.
Fact #2. The numeric keypad was introduced quickly after the computer. This was due to the early need for calculations in computers. When the computer keyboard was introduced, solving non-linear equations with a calculator was becoming easier than ever. Basic calculator programs were often added to early computers as a selling point. To better support this, keypads from accounting calculators were added onto the keyboard.
Fact #3. Numeric keypads are a must-have for anyone who regularly inputs a lot of numbers into a computer. Data entry positions regularly require workers to input large amounts of information, including numbers. This is difficult with the row of numbers provided above the standard keyboard.
Fact #4. These keypads provide a much better option for entering numerical data. The physical reason for this is that the amount of hand movement required to enter numbers using the top line on a keyboard is impractical. From the key for the number 1 on a keyboard, reaching the key for the number 9 requires unnecessary stretching or hand movement to perform.
Fact #5. Networking and systems administration positions will likely need to use these devices. Mathematicians and accountants also favor them for their calculator-like layout. When a lot of basic algebra needs to executed quickly, the keypad is the place to go. Most have additional keys for the most commonly used functions of a calculator. Keys for addition, subtraction, multiplication, and division are standard.
