Answer: 19
Step-by-step explanation:
80 - 23 = 57 signatures left
57 signatures divided by him and his 2 friends
57 / 3 = 19
They need 19 signatures each
20₃ - 11₃ = 20₃ - 10₃ - 1₃
… = 10₃ - 1₃
… = 2₃
Put another way, we "borrow a 1" from the 3¹ digits place:
20₃ = 1(3)₃ - 11₃ = 2₃
But this is just the number 2 (in base 10), which in base 2 would be 10₂.
