Example (a very simple math problem):

x - 5/6 = 7/8 (fractions, here)

Solve for X

it's simple, right - no sweat, yeah? I've done it countless times - it's rather boring.

Add 5/6 to the left to get rid of it, thus - you add 5/6 to the right to carry it over there - which isolates X.

X = 7/8 + 5/6

So in order to add a fraction you find the least common denominator and follow through with the math.

7/8 becomes 21/24

5/6 becomes 20/24

21 + 21 = 41

Answer is 41/24 - you can factor that out further if you want but it's not required.

The book's answer: 15

MMMHMMM.

$100.00 for a book to tell me the answer is 15.

You can check it by plugging in their given answer if you like. 15 instead of X.

15 - 5/6 = 7/8 . . . if you factor that out you SEE it's wrong because 15 - 5/6 is *not* 7/8 . . . maybe on the planet moron it is, but not on Earth with our earthly ways

Stupid ****ing textbook THIEVES.

This isn't the only answer that's wrong, either - I've found 4 that are incorrect so far - and I'm only on chapter 2.

Though I might be insane - I'm sick as a dog with a cold. Maybe I'm wrong - but if so, I'm going nuts.
