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.
thanks for telling me about that...I didn't know how to input my equation.
np. so, first evaluate 1/3 +1/4
i find the LCM of both of the them right? If so it's12
right, so 1/3 = 4/12 and 1/4 = 3/12
that's what I got. yay! okay now we add them it becomes (7/12)
okay great! so what is 7 / 7 / 12?
dividing right 7/7 = 1 and 7/12 = 1.71
huh? no. it is \[7 \div (7/12)\]
you have to be patient with me. I haven't done math in 8 years. :(
\[7\times12/7\] 7 and 7 cancel out. so the answer is 12.
23-12 = 11 is your final answer.
oh...I see what I did wrong. duh!
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
it's weird though, but I don't have an aunt called sally o_o lol, but anyhow, hope this sets things right ^_^
LOL! what does that stand for?
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.
nah, you'll get through with it in no time ^_^
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)
lol, my dear aunt sally statement is better :D
I always used aunt sally
oh well, I was taught bodmas. its all the same.
likewise LOL, I know dhat ^_^
sigh, I miss school lol
lol, yeah. I would be so smart at it now!
yep! >_< and I'd get 100s and As all over the place
