Common Mistakes

MISTAKE: Writing '908' instead of '98' when hearing 'ninety-eight'. | CORRECTION: Remember 'ninety' means 9 tens, so the '8' comes right after the '9'. It's a two-digit number.

MISTAKE: Confusing 98 with 89. | CORRECTION: The order of digits matters. 98 has 9 tens and 8 ones, while 89 has 8 tens and 9 ones. They are different numbers.

MISTAKE: Thinking 98 is a three-digit number. | CORRECTION: 98 only has two digits (9 and 8), so it is a two-digit number. Three-digit numbers start from 100.
