Remember to use the Please Excuse My Dear Aunt Sally acronym: 5x5+5x5+5-5x5 25+25+5-25 the negative 25 cancels the other 25 so you are left with: 25+5 which equals 30

I have a 15 page paper due tomorrow. I finished the paper, and edited it and all, that's not my problem. My cover page is a work of art that I designed and I wanted to put a note on how it relates to my essay. How would I go about doing this? Do I add a page at the back ...

1 and 2 are correct, as far as I can figure out. You would leave number 1 as 2.5, if not a more complex decimal. As a mathmatician, you will always show the decimals to several points out. Scientists don't like this saying that extra decimals just create confusions. If you...

I am not sure what the formula is, but I can tell you that 1/4 multiplied by 80 is not 60. It would be 20. 60 is 3/4 of 80.

Plug the equation in in separate parts. Otherwise most calculators would change the steps up. Try this to start (8/(2^3))-2+(4.1*2). Remember the steps in solving an equation (power, parentheses, multiplication, division, addition, subtraction. In that order).
