What is so special about this calculator? 1) It won't show all those '+' '-' symbols on the screen. 2) It does not have
the equal button which most of the time is not that useful at all ( just press on any of the four key '+' '-' 'x' and '/' to get the answer! ). It is simply an easy and simple to use calculator.

1) Press the first number and then press the '+', '-', 'x' or '/' key to sum, subtract, time or divide any two numbers. Next press the second number and then press any of those four keys again to get the answer. If you wish to add, minus, multiply or divide more numbers then just press any of those keys again and then follow by the number you wish to add and etc.

2) Once you have entered a number then just press on M+ to add the number to memory or M- to minus the number from memory. Press the MR to show the total sum in the memory on the screen or MC to clear the memory.

3) The other features like square root, delete and percent are the same just like any normal calculator function.
