I am in grade 9 math and I hope that this forum will help.
Hello and welcome! I hope you find your time here informative and instructive!
A few tips for getting help:
a) Post the problem in its entirety, and use bracketing symbols to make it clear and easy to interpret. The best option here is to look into the use of $\displaystyle \LaTeX$ for making your mathematical expressions easy to read.
b) Show what you have tried, what your thoughts are about what you should do, etc. Take the time to type out your work rather than uploading a picture of hand-written work. I know I am sometimes just not in the mood to look at hand-written work, and I suspect I am not alone in this.
c) Don't post a bunch of problems all at once. Post one or two at most in a topic. I have seen people (not just here) upload an entire assignment set of problems, with no work shown. It is as if a bunch of dirty laundry has been dropped of at the cleaners, and they will be back later to pick it up at their convenience, laundered, pressed, folded and ready to go. These topics rarely get positive replies.
Note: these are not rules by any means, but merely recommendations for encouraging folks to give you help.
