13+70/5+3x4=81 Enter parenthesis to make this true, show step by step

Thank you for asking our help with your homework assignment. However, there are some rules we have for doing so.
Do not simply retype or paste a question from your book or study material

We won't do your homework questions for you. You were given the assignment for you to learn.

If you come up with your own answer or process and post it for us to critique that is acceptable. If you have some SPECIFIC questions that you couldn't find or didn't understand, we may help with that.
But this is your assignment, so show us you have at least attempted to complete it on your own.

Thank you.

Hint: 4 should not be left alone as it is because 81 is an odd number.

Hi Scott Gem FYI: If I could scan the 10 pages I used to figure out this problem I would have FYI I already took the test and I have to wait another week for the answer which I know I got wrong, Despite all the times I tried to answer this question, I cannot figure it out.That is why I requested help and I did not copy it from my book, I just know the question by heart. Anyway thank you for nothing!

Thank you unknown 008 for the hint!

Excuse me but this site has rules as stated. It doesn't matter whether you copied it remember it. We need to know that you did the work and aren't just asking us to do it for you. If you had reviewed the rules of this site before posting you might have explained why you were asking in the original post.

Don't get upset at me because you didn't follow our rules. That's being rude.
