Numeric keypad

Aka/also known as: numpad, 10-key
A numeric keypad is a bank of keys usually found on the right side of a full-size keyboard featuring keys for inputting numbers and basic operator symbols. Typically found in a 17-key implementation, you get keys for numbers 0 to 9, a decimal key, keys for four operators (/, *, - and double height +), a num lock toggle key, and an enter key. Variants with more keys exist too, with the 18-key variant that adds a backspace key at the expense of making one of the larger keys smaller being a common upgrade. Numeric keypads exist as either a part of a keyboard or as a separate device useful for laptop usage. When num lock is disengaged on PC-compatibles, the numbers and decimal keys become a navigation cluster represented by the secondary legends on the keycaps.
