how does a calculator know all the right answers?

Question

if no human knows everything, who does the programming

Answer 1

most math can be described in rules. in programing the rules the calculator can use the rules on the input. basically, as with all programs it is input and out put... all programing does is tell it what to do with the input.

Answer 2

A calculator does not know all the right answers. It is a specialized computer which takes the numbers input, and the specified function (add subtract divide multiply etc) and performs it on the numbers then displays the answer.

The programming, while not being suitable for a beginner project, is not especially hard.

Also, today, much programming is done with compilers, which can take higher level concepts and convert them to low level 'machine language.'

Since the early 70's, when I saw my first calculator produced by Texas Instruments, and they were fairly simple, the utilities used for programming have advanced steadily. It is sort of like the old expression, moving up by your bootstraps.

My best friend, who I must say is a lieberal, actually believes that microprocessors were given to us by aliens from outer space because he believes that no human could design them. (He also believes that Clinton did not have sex with that woman.)

I started on microprocessors in 1974, and have seen the advances. It is all 'step at a time' advancement and there are humans who can do it.

Answer 3

No human knows everything. No calculator knows everything.
A calculator is a mechanical device that can add and subtract. It doesn't do everything, try to tell it to wash the dishes.

Answer 4

I don't know. Why don't you ask your calculator?

Oh, maybe because your calculator doesn't know all the right answers.
