Oh the beautiful harmony of divisibility rules... until number 7 crashes the party! The grid reads "2 THANK 3 YOU 4 ALL 5 FOR 6 HAVING 7 NOT YOU 8 EASY 9 DIVISIBILITY 10 RULES" - and it's hilariously accurate! While most numbers have simple tricks to check divisibility (divisible by 2 if the last digit is even, by 3 if sum of digits is divisible by 3, etc.), poor number 7 is the mathematical equivalent of that one friend who brings calculus problems to a pizza party. No clean trick, just pure mathematical chaos! That's why only the true math villains among us gleefully apply the test for 7 in calculations. The rest of us just grab a calculator and silently question our life choices.
People Who Apply The Test Of 7 In A Problem Are Psychopaths
