Leave your fear of math behind along with the equations and symbols, we're headed to Ruby-land! On this whirlwind tour, we’ll explore how to write better conditionals with Boolean algebra, figure out how many test cases we need with combinatorics, a mental model for breaking down large tasks with graph theory, and more. You’ll leave this talk equipped to better do your job with some ideas, techniques, and mental models from the wonderfully practical world of discrete math.
