Multiply Divide Q&A

What is a significant figure? How can add, subtract multiply or divide them?

Hi I do not understand senior figures at all! Can you please help me? Zero part of them? When can get into it? I have a test tomorrow and I'll have to round significant figures. For example, how 455.77 round to 456? When you round up or down? My teacher is very clear about this. Thank you very much <3 Thank you guys so much I'm kind of understanding now!

I need help in an extremely easy math question?

Ok, so I want to buy some wall panels. I have enough for 45 feet wall. It is 4 feet wide, and cost about $ 8 each. Do you divide 45 by 4 (because they are 4 feet wide) and then multiplied by $ 8? If not, how find out?

Yes, it is done correctly. Divide 45 feet (the length of the wall) by 4 feet (the width of each panel) and you get 11.25. In fact 12 panels are needed to cover the wall and the end result will be a panel on the left is more than 3 feet wide. Then take your 12 panels and is multiplied by August 12 x 8 = 96 or 12 panels x $ 8 = $ 96
