CaspianXI , 11 months ago (edited 11 months ago) In simple English… A number is divisible by 7 if the difference between 2 times the last digit and the remaining digits is divisible by 7. Examples: Is 14 divisible by 7? 4*2=8. 8-1=7. Check. Is 28 divisible by 7? 8*2=16. 16-2=14. Check. Is 182 divisible by 7? 2*2=4. 18-4=14. Check. Is 1323 divisible by 7? 3*2=6. 132-6=126. Is 126 divisible by 7? 6*2=12. 12-12=0. Check. OP, if I have misunderstood your reasoning, please correct me.
