How do you do the multiplication sign?
The sign of multiplication is x or *
When you are using scientific notation why do you use a x instead of a regular multiplication sign?
Purely a matter of convenience. 'x' is an acceptable character that means "multiplied by", and it appears on the keyboard, whereas the regular multiplication sign doesn't. Well . . . to be perfectly honest, we don't even know what a "regular multiplication sign" is. ======================================== Another contributor agreed: I was just going to ask that, what is a regular multiplication sign? For 50 years I have been using x I think he means when he says regular multiplication sign he means the dot that is used for algebra because x is a variable. P.S. I just learned about scientific notation and asked my teacher the same question. She didn't know.
What do you us to add a calculations up on the keyboard?

Who introduced multiplication and division sign?

Why do they have a multiplication sign?
Why algebra has a different multiplication sign is because they don't want to mix up the American multiplication sign with the variable x. So they use a centered dot for algebra instead of this: x.
