Is This A Typo: "45-year-iold"?

Yes,without a doubt that is a typo. Also sorry about all the people in the comments being condescending.

I feel like this question is a troll.

Yes, definitely a typo.

I mean obviously??? I understand that when learning languages sometimes you can't be sure about things but you gotta learn to go with your gut sometimes. What other explanation could there be?

100% a typo!
