2.13 million dollar comma

after i read the article, "comma quirks irks rogers", i realized the importance of punctuation in sentence structure. Before this, i have always thought that a comma is used to join two sentences and fix run-ons . Everytime i want to join two incomplete sentences, i just use a comma. i never knew that it could change the whole meaning of the sentence. Just because of a simple mistake of the use of a comma, the company lost 2.13 million dollar. That's a very costly mistake for a punctuation error that could have easily been fixed with a little editing.
After reading writing that works, i learned that commas are used to link, enclose, and separate phrases. if we use it right, it can clarify and emphasize how ideas fit together. However, if we use it incorrectly, it can lead to confusion and the reader might misinterpret what you want to say. I've learned that puntuation errors can have a big impact on my writing. So from now on, i will start checking my punctuation in my writing to make sure it is gramatically correct and make sure it doesn't alter the meaning of the sentence.
