What order will result a final output of 131,065 when the first input is 64

I think the input referred to here is when you input it to the calculator. Looking at the given information, the input is less than the output. So, we can deduce that the operation used would magnify the input. That is either addition or multiplication. However, since 131,065 is not an exact multiple of 64, the answer should be addition. The second input must be:

64 + Second input = 131,065
Second input = 131,001
