Mr. Digit wanted to assign a number to each student in his class. He could only use the digits 2,3,and 6 and each student's number had to have three digits. Can he find enough numbers for all 25 students if repeated digits are allowed? Will there be any extra numbers?

  1. There may be a shortcut to finding this answer -- but you can do it this way:

    222
    223
    226
    232
    233
    236
    262
    263
    266
    Do the same with numbers beginning with 3 and 6.

  2. Or you could just count how many numbers Ms. Sue provided and multiply by three for your total number of possiblities.
