Answer:
As this is a super-serious totally relevant question, I will do my best to answer.
Explanation:
This has been erroneously mislabeled as mathematics instead of English because this is clearly a grammar problem.
The first error is capitalization at the beginning of the sentence.
<em><u>Y</u></em><em>ou aint even saying why is yes you chould try explaining it better next time.</em>
The second problem is the punctuation in multiple places. An apostrophe is needed in <em>aint</em> to make it ain't, and a period is needed after <em>yes</em>. Because of that period, you must capitalize that second <em>you.</em>
You <u>ain't</u> even saying why is <u>yes.</u> <u>You</u> chould try explaining it better next time.
The next error is a missing word to improve cohesiveness and make the sentence grammatically correct. You must add <em>it </em>after <em>why</em>.
You ain't even saying why <u>it</u> is yes. You chould try explaining it better next time.
The final thing to fix is a simple misspelling. Should was typed as chould which can be fixed with the easy changing of a single letter.
You ain't even saying why it is yes. You <u>should</u> try explaining it better next time.
And there we go! Your sentence has been corrected and it is now a grammatically correct and well-written sentence.
