Mathwizard likes to play a fun number trick on her friends. she tells them to think of a number. she then tells them to subtract their number from 2 and multiply the result by 5. to this product she tells them to add half the difference when 24 is subtracted from 12 times their original number. (a) if i use the number 8 and follow mathwizard's steps, what number will i get? (b) if you correctly apply mathwizard's steps to your favorite number, and then tell mathwizard your result, how can mathwizard quickly figure out what number you started with?
