Needs moar brackets.
(6 / 2) * (1 + 2) = x
EDIT: Was already answered...
The brackets are important
Boom, an easy explanation given on Google (and saving me time from typing):
I thought am all alone here bro
No, by this stage you have resolved the contents of the brackets so the brackets should no longer be in the equation, by this stage it should be a simple 6 divide by 2 multiply by 3 = 9
Only if you assume that 6/2(1+2) can be re-written as
which would be a pretty far stretch IMO. You can't just decide on any given problem that / is the same as saying "6 OVER 2(1+2)" just because you feel like it. If you mean / to say that everything to the left of it is OVER everything to the right of it then just write it like that.
Then there's no room for interpretation which is crazy to even consider as a possibility in math.
I typed it out the way I was taught. Just be glad I didn't type it out how my comp sci teacher taught....lol. That class was a PITA....and misnamed. It was actually math + programming (or using programming to solve mathematical equations).
I'd pay to see what would happen if they put up a "determine if the sum of the infinite series ((-1)^n)/((n^5)+3n!)) absolutely converges, conditionally converges or diverges"
Facebook responses would = none. LOL
Math is fun.. I love the way the number 9 keeps popping up in math too..the magic number!
For instance, take any random number you want, two digits or more (as long as it won't cancel itself out to zero in a subtraction because it contains all the same digits.. eg: 4444)
My chosen number is 7902.
Mix those digits up into any other order, and subtract the smaller from the larger.
From your answer, add the digits together and you'll get 9.. (or a number which contains digits that will add up to 9).. every time..
and so on...
edit.. sorry for off topic a bit
It's math, so technically it still pertains to the topic....just rather loosely....and contains the answer to the equation.
I have a love/hate relationship with math. I love it because of it's ability to solve problems....hate it because so many fail to understand it's principals...
math is cool.. i just wish i had better time, professors and wisdom to absorb it (my advanced math class - i.e. Bernoulli's EQ, Fourier transform, etc).
you wouldn't want to use the division sign in higher degree or complicated maths expressions. always use fraction signs. if you use the division signs it will run into problems like this
