Submitter: [This] was in the library of my high school, a large school in a wealthy suburb, until May of this year! This book promises to teach tricks for calculators. However, there is a lot of talk about “overloading” the calculator with large numbers, like anything over eight digits, or giving it “lockjaw” (Huh?). Most modern calculators can handle at least twelve, and some can go even higher by displaying in scientific notation, so that’s no longer very accurate. There are some tricks that involve that thing where you flip the calculator upside down to spell words. Sadly, it does not mention that venerable classic of the calculator alphabet genre, 55378008. Graphing calculators, (i.e., the calculators most likely to be owned by the kind of people who find this stuff amusing) have moved away from the traditional seven-segment display and thus don’t make those letters anymore.
Holly: A reasonable choice for libraries in 1975, but this particular high school can probably do better. Kids are more interested in playing 2048 or Candy Crush than spelling 55378008 on calculators.

(Above) Submitter: I think this was after a riddle where the answer was 710 (oil). At first I thought with the cane and round sunglasses that he was supposed to be a blind guy as well as an oil sheik.
