Common Mistakes

MISTAKE: Writing 107 or 17 when asked to write One Hundred Seventy. | CORRECTION: Remember 'One Hundred' means 100, and 'Seventy' means 70. So, 100 + 70 = 170. The '0' at the end is important.

MISTAKE: Confusing 'seventy' (70) with 'seventeen' (17). | CORRECTION: 'Seventy' has 'ty' at the end, meaning it's a multiple of ten. 'Seventeen' has 'teen' at the end, meaning it's between 10 and 20.

MISTAKE: Reading 170 as 'one seven zero' instead of 'One Hundred Seventy'. | CORRECTION: When reading numbers, we group them by place value. 170 is 1 hundred, 7 tens, and 0 ones, so it's 'One Hundred Seventy'.
