What are IT/ICT/programmers the whole day doing at their offices?

[TheCreative]

Hello everyone

I have some programming experience, so I have a taste for what a program is,
and I like mathematics/physics.

I always ask myself what are the people who calls their selves programmers/ICT/IT managers etc… doing the whole day at their offices?

Can someone please give me few examples of what they are doing, or let’s assume
that I’m one of them (not senior sure, but a beginner), give me few examples of the projects or the work that I must do at such offices.

Take Google for an example what are the employees doing the whole day their?
Are they solving mathematical equations (Linear Algebra, Differential Equations, Integration etc…) or are their many other things to do?

Which skills should someone have to enroll in such offices, I have heard mathematics, but which kind of mathematics?
Are all of those people who calls their selves programmers (or work in such offices) really good in mathematics and algorithms? Or is there other kind of work that is not based on mathematics and algorithms?

What are managers? (economically and software)

Please give explanations, books recommendations for self study etc…
