10 a. the answer would be 7.2 c 13.6 - 6.4 = 7.2
12.6 ...if it was rounded, it was rounded to the nearest tenths.....because ur 6 is in the tenths place
if it was 12.67 rounded, then it would have been rounded to the nearest hundredths place because ur last digit is in the hundredths place
and if it was 12.678 rounded, then it would have been rounded to the nearest thousandths place because ur last number is in the thousandths place
u get it ?
Math to me is very complicated. I know that I need it in life, but when have you ever needed to find the square root of the distance from the sun to mars on a normal day-to-day basis? But jokes aside, I know that I do math without thinking about it. It is important, even for the jobs that you would think that you would NEVER need it (even English teachers do it, haha.) Overall, math is kinda iffy. In my opinion, you can't live with it, but you <u>really</u> can't live without it.
