Are you sure???
My wooden Russian brain is telling me this:
-25/27*(5/3) + 8/9 = -25/27 * 5/3 + 8/9 = -0.65432098765
which is NOT equal to 1/3.
Where did you learn the math if you don't know what
-25/27*(5/3) is ABSOLUTELY EQUAL to -25/27 * 5/3?
Wanna check? Go to
http://instacalc.com/ and copy-paste both formulas there. I mean these:
1) -25/27*(5/3) + 8/9
2) -25/27 * 5/3 + 8/9
You may believe me or not, but you'll get THE SAME result which is
-0.65432098765. As you can see,
-0.65432098765 IS NOT EQUAL to 1/3.
Now copy-paste there the right one:
-25/27 * 3/5 + 8/9
...and you'll get the correct result 0.3(3) which is 1/3.
Ah yes... you may also use the brackets if it really does matter for you, e.g.:
-25/27 * (3/5) + 8/9
-25/27 * (3/5) + (8/9)
(-25/27) * (3/5) + (8/9)
(-25/27) * (3/5) + (8/9)
(-(25)/27) * (3/5) + (8/9)
etc...
