\[(34+18\times 2)-(5\times 2+7)\]is a better start
anonymous
  • anonymous
then maybe a calclulator
anonymous
  • anonymous
actually get none of the above could there be a typo there?

can you post a screenshot of the question?
anonymous
  • anonymous
maybe i read "18.q" wrong not really clear there
supercait10
  • supercait10
yea i'll get a screenshot hold on
anonymous
  • anonymous
ok

why is this same question posted again?
supercait10
  • supercait10
Because my teacher gave me a second chance at this question and he said if I couldn't figure it out after five tries he said I can ask for help so I am
anonymous
  • anonymous
Ah 5 to the power of q, that means the following \[5^2 = (5)(5) =25\]
anonymous
  • anonymous
oooh !!
anonymous
  • anonymous
nothing like the equation editor
triciaal
  • triciaal
but we can't help you if the question is not clear.

Please use "^" to indicate to the power of next time :)

i just posted a file showing the test look at it to understand it

\[(34+18\times 2)-(5^ 2+7)\]
anonymous
  • anonymous
i guess you are supposed to be practising the "order 'o operations" right?
anonymous
  • anonymous
you know what to do first?
supercait10
  • supercait10
yup now starting Algebra and haha no my weakest link in school is math I barley passed Math last year so this is beyond me I better understand History then i do math
anonymous
  • anonymous
square first
anonymous
  • anonymous
i.e. compute \(5^2=5\times 5\) don't think too hard here
anonymous
  • anonymous
what do you get?
supercait10
  • supercait10
hold on had to get a drink
anonymous
  • anonymous
yeah i need one too maybe some bulleit rye
supercait10
  • supercait10
lol maybe
anonymous
  • anonymous
did you manage to compute \(5\times 5\) yet?
supercait10
  • supercait10
yea
anonymous
  • anonymous
care to share it with the class?
supercait10
  • supercait10
yea
anonymous
  • anonymous
...
supercait10

25
anonymous
  • anonymous
whew
anonymous
  • anonymous
so now \[(34+18\times 2)-(5^ 2+7)=(34+18\times 2)-(25+7)\]
anonymous
  • anonymous
now lets do the multiplication \(18\times 2=?\)
supercait10
  • supercait10
36
anonymous
  • anonymous
ok so now we are at \[(34+36)-(25+7)\] add in each parentheses what do you get?
supercait10
  • supercait10
(34 + 36 = 70) (25 + 7 = 32) all together = 102
anonymous
  • anonymous
there is no such mathematical operation as "all together" is there?
anonymous
  • anonymous
you should be looking at \[70-32\]
supercait10
  • supercait10
i'm tired so I'm really not paying attention to what I type
anonymous
  • anonymous
then go to bed and do this arithmetic some other day

  • supercait10
i can't I have to have this submitted by 11:30 tonight or I fail it
