the question is not clear. Use the equation toolbox and write down your question. You can type in the equation use the Equation button just underneath this area.

np. so, first evaluate 1/3 +1/4
anonymous
  • anonymous
i find the LCM of both of the them right? If so it's12
anonymous
  • anonymous
right, so 1/3 = 4/12 and 1/4 = 3/12
anonymous
  • anonymous
that's what I got. yay! okay now we add them it becomes (7/12)
anonymous
  • anonymous
okay great! so what is 7 / 7 / 12?
anonymous
  • anonymous
dividing right 7/7 = 1 and 7/12 = 1.71
anonymous
  • anonymous
huh? no. it is \[7 \div (7/12)\]
anonymous
  • anonymous
you have to be patient with me. I haven't done math in 8 years. :(
anonymous
  • anonymous
\[7\times12/7\] 7 and 7 cancel out. so the answer is 12.
anonymous
  • anonymous
23-12 = 11 is your final answer.
anonymous
  • anonymous
oh...I see what I did wrong. duh!
anonymous
  • anonymous
heh. \[a \div b = a \times 1/b\]

So if I was going to do this problem..... (0.95-0.68)x6. I would do whats inside the parenthesis first and complete it before I move on to multiply. That rule goes for all with parenthesis......

yes. you should always follow order of operations http://en.wikipedia.org/wiki/Order_of_operations#The_standard_order_of_operations

PEMDAS Please, Excuse, My, Dear, Aunt, Sally~~~

P - Parenthesis, E= exponents, M = Multiplication, D= division, A = addition, S = subtraction ^_^ and + always start computing from left to right
anonymous
  • anonymous
also, BODMAS.
anonymous
  • anonymous
it's weird though, but I don't have an aunt called sally o_o lol, but anyhow, hope this sets things right ^_^
anonymous
  • anonymous
LOL! what does that stand for?
anonymous
  • anonymous
yeah. I am still learning how this all works again. We are working on equations and decimals, and word problems. I am having such a hard time with this stuff.
anonymous
  • anonymous
nah, you'll get through with it in no time ^_^
anonymous
  • anonymous
B Brackets first O Orders (ie Powers and Square Roots, etc.) DM Division and Multiplication (left-to-right) AS Addition and Subtraction (left-to-right)
anonymous
  • anonymous
lol, my dear aunt sally statement is better :D
anonymous
  • anonymous
I always used aunt sally
anonymous
  • anonymous
oh well, I was taught bodmas. its all the same.
