text: how to convert numbers from numerical numbers to binary.? please explain binary is nothing more than powers of two. for example, the number 37 in decimal is 3 * 10 + 7. in binary, it would be 100101, which is 1 * 2^5 + 1 * 2^2 + 1, or 32 + 4 + 1. to convert a number to binary, you need to divide it by two, and then arrange the consecutive remainders in reverse order.  let's take 37 again:  37 / 2 = 18 r 1 18 / 2 = 9 r 0 9 / 2 = 4 r 1 4 / 2 = 2 r 0 2 / 2 = 1 r 0 1 / 2 = 0 r 1  and there you have our binary number once more: 100101 (the remainders in reverse order).  good luck.
