Convert number system
It is difficult for me to convert number system.
Such as convertion from hexadecimal number 2DCH to decimal. God knows! I have not been touched math for five years, I forgot math and I can't figure out.
But it will set the paper about convert number system at least one question and I decided to give it up.
(数制转换对于我来说太难了！
例如，把十六进制数2DCH转换为十进制数。天知道！我已经五年没学数学了，都忘了，我算不出来。
但是在本月底的考试中将会出至少一道关于数制转换的试题，我决定放弃它了。)

Oh I see! 'H' doesn't means number. Thanks to your explanation, Shudong. Thank you very much! :)

Converting from a hexadecimal number to a decimal number is extremely simple. For 2DCH, the suffix 'H' means this number is a hexadecimal number. In 2DCH, 'C' means 12 and 'D' means 13. So the decimal number corresponding to 2DCH is
2x16² + 13x16¹ + 12x16º = 732.
