Give me a valid reason as to why we have absolute value.

There's no reason. Absolute value is for cucks.

Because, in real world applications, it is useful to be able to measure the absolute magnitude of a quantity with respect to another quantity. For example, when trying to model and predict real world events which require logarithms and exponents

If you meant in terms of mathematics, then you should stop being an autistic shitposting faggot and explicit state it instead of assuming we know what you mean.

Doesn't make sense to have an imaginary valued step function when you integrate a real valued function. Fucking amateur

BY DEFINITION OF ABSOLUTE FUNCTION

f(x) = x, for x >0 (i.e positive values of x)'
&
f(x) = (-x) for x<0(i.e negative values of x)
thus this V shaped graph.
