### About the Number 4,242 (four thousand two hundred forty-two)

MathBabbler does a lot with the number 42 [the "Answer to Life, the Universe, and Everything"]. Examples: BARS (Basic Arithmetic Road Signs) have something call an rs42Eval and BADs (Basic Arithmetic Dates) have a bad42Eval. These "evals" involve finding expressions using the numbers found in road signs and dates that evalute to 42. On 21 September 2016, MathBabbler turned 4242 dates of age.
