ok:
my textbook for a class I'm taking has me doing some really basic base 10 -> binary conversions and vice versa. For example, I'm supposed to convert the number "5" to binary. I get "101"
Code:
1x2^2 + 0x2^1 + 1x2^0
for my answer. The book says that my answer should be 0101. This doesn't make any sense to me and I am wondering if I'm wrong or if the book is just weird.
