Common Mistakes

MISTAKE: Confusing ninety-seven with seventy-nine or ninety-six | CORRECTION: Remember that 'ninety' means 9 tens, and 'seven' means 7 ones. So, 97 is 9 tens and 7 ones, not 7 tens and 9 ones (79) or 9 tens and 6 ones (96).

MISTAKE: Thinking ninety-seven is an even number | CORRECTION: An even number can be divided by 2 with no remainder. Ninety-seven leaves a remainder of 1 when divided by 2, making it an odd number.

MISTAKE: Believing ninety-seven is a composite number | CORRECTION: A composite number has more than two factors (1, itself, and others). Ninety-seven is a prime number because its only factors are 1 and 97.
