In an education video result is 81. Can you explain why?

Because, you set it as a base 3 number. From the right most number going left (right to left) you have the ones place, threes place, nines place, twenty-sevens place, eighty-ones place. The only place that has a value is 81. Try running the following to help you understand: print(int("1", 3)) print(int("10", 3)) print(int("100", 3)) print(int("1000", 3)) print(int("10000", 3)) since it's base 3 each place can hold 1 of three values (0, 1, or 2) which is then multiplied by its place and added to the next place and so on. So, print(int("202", 3)) would equal (2*9)+(0*3)+(2*1) = 20

Because the string is parsed in base 3
