Do you use certain numbers on a daily basis? Why not program them into your calculator so that you don't have to keep entering them in each time you want to use them? That is exactly what this calculator does.

Calculon was built to solve the problem of repetition. Enter in all your personal numbers as variables and listen as your fingers thank you for saving them time.

Also, we have built in a way to turn off the 'Order of Operations' that happens on most every calculator. When you turn this off, all your calculations happen from left to right, in exactly that order. This is helpful when you are adding in multiple checks, receipts, etc. so that you get the right calculation ( PEMDAS: 5 + (3 + 2) * 2 = 15, Linear: 5 + (3 + 2) * 2 = 20 ).
