Answer 1

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.

Answer 2

\[23-7\div(1/3+1/4)\]

Answer 3

thanks for telling me about that...I didn't know how to input my equation.

Answer 4

np. so, first evaluate 1/3 +1/4

Answer 5

i find the LCM of both of the them right? If so it's12

Answer 6

right, so 1/3 = 4/12 and 1/4 = 3/12

Answer 7

that's what I got. yay! okay now we add them it becomes (7/12)

Answer 8

okay great! so what is 7 / 7 / 12?

Answer 9

dividing right 7/7 = 1 and 7/12 = 1.71

Answer 10

huh? no. it is
\[7 \div (7/12)\]

Answer 11

you have to be patient with me. I haven't done math in 8 years. :(

Answer 12

\[7\times12/7\]
7 and 7 cancel out. so the answer is 12.

Answer 13

23-12 = 11 is your final answer.

Answer 14

oh...I see what I did wrong. duh!

Answer 15

heh. \[a \div b = a \times 1/b\]

Answer 16

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......
