Hi, I needed to solve a problem today and someone told me the answer was converting a number to an Octal Base number. I didn't even think about that because I didn't know what one was. People on another forum told me that is covered in like 8th grade math. So I was wondering, does anyone know of some good books that I can learn math from from beginning, to algebra to calculus? Or what math I need to know? I don't want this to happen again where my math skills are so bad that I cannot even solve simple programs due to lack of math knowledge. Thank you. Derek:D
