It's the positive value of a number, it removes the negative sign from any negative number leaving it positive.
Examples:
Absolute value of -4 is 4
Absolute value of -78 is 78
Absolute value of 0 is also 0

For real numbers, what Mo Hani said.
For complex number it is the distance between the position of the number on the complex plane and the origin.
For a complex number z = a + b*i, using Pythagorean's theorem we get the absolite value r = |a| = sqrt(a^2 + b^2).
Since real numbers are compelx numbers with b = 0, we get the formula |x| = sqrt(x^2) which is the number without the sign.

It simply means ignore the native sign, take it as a positive number.
E.g.
find the absolute value of -2*3
the result is simply 6.
that is you neglect the negative sign

Absolute value on real numbers is a function that has the formula (sorry for the layout):
x , if x >= 0
/
f(x)=|
\
-x , if x < 0

it simply means the positive value of any number, that is abs(7)=7 and abs(-7)=7
