Question

what is | | in math?

Answer 1

| | denotes the absolute value of a quantity or function

Answer 2

its the absoulte sign so if you have |-5| the answer is 5

Answer 3

so if I have |-5|=5 because the magnitude of the quantity is 5 and the minus sign (or lack thereof) just tells us whether we are to the left or right of 0 respectively

Answer 4

Haha nice @shay16 picked the same number :D

Answer 5

haha

Answer 6

Also if we are talking about a function... perhaps we are only interested in the magnitude of the result given an input.... so the graph of f(x) may be a curve that goes above and below the x axis but the graph of |f(x)| is strictly above the x-axis (or on it as in =0) at all times.

Answer 7

thanks
