How many times have you had an exam returned and thought to yourself, “Well, that was stupid of me.” Many times re-reading the directions given on an exam or double-checking your work can make a substantial difference in your grade. In the “real world”, the consequences of mistakes can be more severe. This is exemplified in a comic strip titled Los Alamos from XKCD.

In the strip, the characters discuss the important implications of the test they are about to conduct, and the dire consequences of the test if their math is incorrect. One character then asks, “Is it ‘SOH CAH TOA’ or ‘COH SAH TOA’?” Always remember to check your work.
