how to type absolute value symbol

[BM30003700]

Help; trying to send homework problems by email to my son; can't remember how
you type the "absolute value" (vertical bar) symbol on either side of a number.

Stan will probably direct you to his FAQ, but I personally prefer to see
any such functions rendered as they are in most computer languages. I
often cut and paste problems to the computer algebra system Maple, and
in its language the absolute value of x is rendered as abs(x).
Similarly, the square root of x is sqrt(x), but the cube root of x is
x^(1/3).

BTW, assuming that your son, like the overwhelming majority of kids
today, knows how to use a computer, why can't he post his own questions?
We see this not infrequently in this group--parents posting questions on
behalf of their (presumably quite capable) children.

how about this: | 3 | ?

I did that by typing the key (shifted) on MY keyboard at the right end of
the 2nd row of keys. Unshifted, it is a \ .

I use Maple too.

Next year I am going to switch back to Mathematica, so they become
Abs[x], Sqrt[x], and x^(1/3).

Sometimes I paste the expression into a C program too, and they become
fabs(x), sqrt(x), and pow(x, 1.0/3.0).

I may also paste the expression into the HOL theorem prover if the
question is a proof question, and they become abs x, sqrt x, and root
3 x.

Finally, if the expression looks complicated, I probably ask LaTeX to
display it in ordinary math form for easier reading, and they become
|x|, \sqrt{x}, and \sqrt[3]{x}.

So, every time anyone asks a question, I personally prefer to see each
expression rendered in all five computer languages I personally use.
Tee hee hee.

They're not my FAQs. I speak as the perfect disinterested party when I
suggest that you read 'em.

Did you even read the question she's sending the problems to her kid, so why the kid ask the question? Also your trying to get knocked tf out by being a smart ass.

| number |

The symbol is on the standard keyboard with the back-slash ---
above the right-side "Enter" key

The absolute value "bar" is on the standard keyboard.ase on the key
above the right-side "enter" key.
It's the upper c
