Common Mistakes
MISTAKE: Writing 82 as 'eighty-two' with a hyphen, but confusing it with 'eight and two' which is 10. | CORRECTION: Remember that 'eighty-two' means 8 tens and 2 ones, not 8 plus 2.
MISTAKE: Misreading 82 as 28. | CORRECTION: Always pay attention to the place value. The '8' is in the tens place, and the '2' is in the ones place.
MISTAKE: Forgetting the sequence and placing 82 after 83. | CORRECTION: 82 comes between 81 and 83. Think of it as counting forward: 80, 81, 82, 83.
