Tips

Intro

math abs drops the sign.

(-3) | math abs

math sum adds a list.

[1 2 3] | math sum

Basic

Sum, then take the absolute value.

[1 2 3] | math sum | math abs

math avg and math round meet at an integer.

[1 2 3 4] | math avg | math round

Intermediate

Sum, convert, and count.

[1 2 3 4] | math sum | into string | str length

Take abs inside a closure, then sum.

[1 2 3] | each {|n| $n | math abs} | math sum

Advanced

Four math and text steps.
