: : a problem like the following:
: : -43+(-5)/(-12)
: : --------------
: : 56/(-8)-(-3)
: : Is always reffering to devision, correct??
: : The bottom problem once evaluated, divided by the top???
: ****************************
: I think you are missing a pair of parentheses around {-43+(-5)}. If not -- answer will be different
: The expression is generally written as (in text format)
: [{-43+(-5)}/(-12)]/[56/(-8)-(-3)]
: =[{-48-5}/(-12)]/[-7-(-3)]
: =[{-48}/(-12)]/[-7+3]
: =[4]/[-4]
: = -1
: Watch those parentheses......
well no, as how I have written the problem there is the correct way. At least according to my text book :).
The answer for that particular one is:
-43+(-5)/(-12) = -42.58333333
56/(-8)-(-3) = -4
-42.58333333 / -4 = 10.64583333
RND off to 4 S.F. = 10.65
Thanks for the help.....
