Operator error Memes

That Texas Instruments calculator showing 10+10*2=30 is the mathematical equivalent of finding contamination in your control sample. The calculator isn't broken—it's just following order of operations (PEMDAS) where multiplication happens before addition. The correct answer is 30, not 40. It's like telling a grad student to "heat the solution then add the catalyst" and they add the catalyst first because they didn't read the protocol properly. Classic operator error masquerading as technology failure.
