I realized that I needed some help with some regular signs. I use them all the time, but i need to know what their names are in english, can someone please help me?

These are the signs:

* What is it called in general, and what it is called when used in math, to multiply numbers?

; What is it called in English?

( and ) ?

[ and ] ?

> and < in mathematical terms?

Under_the_line, how do you say _ ?

! ?

“ two dots over the word, and what it is called when a word is “within” ?

% ?

: ?

‘ what it that dot called?

I also have some questions about different signs in programming terms and mathematical terms:

!= how do you say that in programming terms?

>= how do you say that in programming terms?

/* when words are */ within “invisible”-signs in programmingcode, how do one say it?

With kind regards
