Now show us your work for one question. Do not show three questions at the same time.
Try to write out your solution in a clear orderly fashion with words explaining what you are doing.
No one will be willing to try and follow what you have shown in the post above.
Pick ONE problem and present your best attempt at working that problem in a clear and organized way.
If you turn in something like what you have shown for grading, the grader should just give you a zero and move on to someone that cares about their grade enough to present something worth grading.
