Sure thing, honey. To convert 31 from base 10 to base 2, you divide 31 by 2, which gives you a quotient of 15 and a remainder of 1. Then, you keep dividing the quotient by 2 until you reach 0, while keeping track of the remainders. The remainders, read from bottom to top, give you the binary representation of 31, which is 11111. Voilà!
