[1] The assignments and tests are good measures of how much I’m learning.

According to Fermat’s little theorem, what is the value of 3374(mod 11)?

The octal expansion of the decimal number 109 is ___________eight. Only type the digits; do not include the base.

The pet shop in Mochdewton sells only guinea pigs and hamsters. Each guinea pig costs twice as much as a hamster. A local elementary school purchased 5 guinea pigs and 3 hamsters. If the transaction had been for 3 guinea pigs and 5 hamsters, the cost would have been $10 less. What is the price of a guinea pig?  [GuineaPig] What is the price of a hamster?   [Hamster]   Adapted from “The Lady or the Tiger? and other logic puzzles” by Raymond M. Smullyan
