Common Mistakes

MISTAKE: Writing '403' when asked to write forty-three | CORRECTION: Forty-three means 4 tens and 3 ones, which is '43'. '403' is four hundred three.

MISTAKE: Confusing forty-three with thirty-four | CORRECTION: Forty-three is '43' (4 tens, 3 ones). Thirty-four is '34' (3 tens, 4 ones). The order of digits matters a lot.

MISTAKE: Adding 4 + 3 to get 7 when asked for the value of 43 | CORRECTION: 43 is the number itself, not the sum of its digits. The '4' in 43 represents 40 (four tens), and the '3' represents 3 (three ones).
