How would this sentence best be punctuated? At the age of twenty si she became a neurosurgeon

I think it would be punctuated like this: "At the age of twenty, she became a neurosurgeon." I'm assuming "si" is a typo lol

have a great day!

At the age of twenty six, she became a neurosurgeon.

Explanation:

A comma is always added when the reader should take a pause. Correct spelling should also be included so the text is legible. Periods are used at the end of sentences.

theres no poem include that
