\cdot all the way (except e.g. cross-product for vectors, I’m not an anarchist)
Same same, cdot is nice and clear
As someone that grades undergraduates, I’m happy that they not use the letter “x” to imply multiplication.
I don’t understand why we teach that to children, just to turn around and tell them not to do it a few years later.
I suppose kids aren’t great at centering a dot. But they could draw a six pointed * as easily as an x, it’s one more line.
I need 'em both. Not everything I multiply is a number.
dot product vs cross product
(1)(3)(5)
Fight me. Also, one of these is a function
I use asterisk.
In LaTeX? You really are a rebel.
\cdotmaster race.\timesusers should just use Microsoft Word (unless it’s for a Cartesian product or for cross product, of course)times is for cartesian product, cdot if i feel like it
\cdotfor matrix multiplication and the dot product,\timesfor cross product and nothing (or*, if I want to write it explicitly and have no convolution in the expression) for regular multiplication.or *, if I want to write it explicitly and have no convolution in the expression
But why
‘*’ is commonly used for multiplication in computer programming, so it’s probably that. Also in your calculator app
** for power?
^for power.**is usually in a programming setting (but it‘s usually a method and not an operator there.)
This is the way
I use
\timesand redefine it as\cdotPeople using the cross for scalar multiplication are insane
How about nothing at all
(
Depends on whether I want a scalar or vector, sine or cosine
\cdot for vector dot products, \times for multiplying plain numbers, whatever i feel like for anything else
edit: dropped the dot in vector dot product, my bad
Vector dot products go with dot, cross with times.
yeah i accidentally left that out
