Lisa is a tax accountant. she needs to enter many numbers. to enter these numbers, she should use the numeric keypad on the right side of the keyboard.
When entering many numbers at a time, using the keyboard that is just for numbers on the right side of the full keyboard is a much quicker way to complete the task. When you are able to use one hand to type them all without accidently hitting a letter key, you can be more efficient and accurate.
