satellite's question: Let n be positive integer. If we divide n by 3, the remainder is 2. If we divide n by 5, the remainder is 1. What is the smallest possible value for n?

3|n-2 5|n-1 n-2=3*q n-1=5*r 3q+2=5r+1 3q+1=5r so the smallest integers so this is true are q=3 r=2 that is n=11

i really don't think i have the personality for math anymore since i only really enjoy number theory i should probably look into computer science or cryptography
