Suggestion: Make base ten chart showing ones, tens, hundreds, thousands etc something like this using both names and exponents Lets convert 28 to binary for example: 10,000's 1000's 100's tens ones 10^4 | 10^3 | 10^2 | 10^1 | 10^0 | | | | | 2 | 8 | | | | | | | | | | | | | | | | | | | | | | | | | 16's 8's 4's 2's ones | 2^4 | 2^3 | 2^2 | 2^1 | 2^0 | | 1 | 1 | 1 | 0 | 0 (16+8+4=28)=28 | | | | | | | | | | | | | | | | | | | | | | | | If you need more help, then let me know and I can expand on this. I might suggest a calculator such as the HP 6s has binary, octal and hexidecimal conversion keys on them. I would suggest using an aid like that to help. The HP 6s is also a very nice inexpensive scientific calculator suitable for all science classes.
