Most recently today? Addition. And counting. This isn't "snark", I work in BI. Counting things and knowing what to count is half the job.

Euclidean gcd algorithm to determine colinearity of points on an integer grid. Double precision slope/intercept fails here.

For production code well, If (p then q) = (NOT p or q)
