Common Mistakes

MISTAKE: Confusing 37 with 73. | CORRECTION: Remember that the '3' in 37 is in the tens place (meaning 30), and the '7' is in the ones place. In 73, '7' is in the tens place (70) and '3' is in the ones place.

MISTAKE: Thinking 37 is an even number. | CORRECTION: An even number ends in 0, 2, 4, 6, or 8. Since 37 ends in 7, it is an odd number.

MISTAKE: Trying to divide 37 by numbers like 2, 3, 5, or 10 and getting a whole number. | CORRECTION: 37 is a prime number, so it can only be divided evenly by 1 and 37 itself. All other divisions will result in a remainder or a decimal.
