One way is to perform the final calculation differently depending on the value of Key_COUNT.

For example, when Key_COUNT is 4 then "Result = Key_ADD[0] * 1000 + Key_ADD[1] * 100 + Key_ADD[2] * 10 + Key_ADD[3]" is correct.

But for Key_COUNT = 2, "Result = Key_ADD[0] * 10 + Key_ADD[1]".

Another way would be to keep a running total of the result as the keys are entered. Each time a new on is entered, the existing result needs to shift one decimal place and the new key result becomes the lowest digit.

Hi kg300, attached simplified flowchart might help.
The target device you are using will not have enough ram to compile either flowchart.
the * key is used to clear the result
