Calculator

[johnny1980]

I had purchased a calculator [amazon, UK an online e-retailer] which allows me to key in financial calculations similar to those I can try to work out with spreadsheet solutions.

I do get a conjecture of answers there is a common concern that the mathematical calculations need more standardization this was confirmed when talking to other technicians as well.

I do not wish to re-program its electronics, I am not even aware of the right programmers to use which would require a few million euros of investment to setup a proper manufacturing or servicing plant at least for now I wish to find common answers to financial questions I have as I cook the books and try to outsmart the team of arrogant accountants who think they are more competent than I am because they have studied a book by heart and obtained a post-graduate qualification in some topic, so they feel on top of the world for a few days after they have celebrated their award, motivating I would say.

The batteries it takes are small I would have appreciated if the manufacturer had thought of a solar power input, this is common place amongst cheaper forms of calculators, since we live in an island where the sun has a natural source of light and energy, so this helps us save the environment from batteries as well.

A mathematical verification algorithm would be interesting, since even though calculations such as net present value are openly documented in textbooks, there may be variances that inspire reprogramming.

I think a graph generator is interesting to see in certain mathematical verifications and whilst understanding this is not a graphing calculator maybe one can devise a separate one that includes combined functions since math is quite a difficult topic nowadays. 

I think most people do not calculate many people are too lazy to think.
