3. After 60, you count 61, 62, 63, 64, 65, 66, 67.
4. The very next number after 67 is 68.
5. So, 68 is the number we reach after 67 when counting.

Common Mistakes
MISTAKE: Writing '608' instead of '68' for sixty-eight. | CORRECTION: 'Sixty-eight' means six tens and eight ones, which is 68. '608' is six hundred eight.
MISTAKE: Confusing 'sixty-eight' (68) with 'eighty-six' (86). | CORRECTION: Pay attention to the order of the digits. 'Sixty' means 6 tens, 'eight' means 8 ones (68). 'Eighty' means 8 tens, 'six' means 6 ones (86).
MISTAKE: Thinking 68 is a single digit number. | CORRECTION: 68 is a two-digit number. The '6' and '8' are both digits, but together they form one number, 68.
