15 + 19 = 36

According to my Math II SAT II study book, 15 + 19 = 36.

 

WHAT!?

 

I think their editor DIED midway through working on the book. So many of the problems are so screwed up...

 

Like the one where they use the 30-60-90 right triangle pattern. Okay, fine. HOWEVER THE SIDE OPPOSITE THE 30 DEGREE ANGLE CANNOT BE LARGER THAN THE SIDE OPPOSITE THE 60 DEGREE ANGLE! Yeesh! Side opposite the 30 degree angle is a and the side opposite the 60 degree angle is a root three, NOT THE OTHER WAY AROUND.

 

And don't even get me STARTED on the superscript mistakes. The pattern is NOT a to the power of n, minus one. It's a to the power of (n minus one) dangit! Not only is the n supposed to be in superscript, so is the minus one! You don't raise a to the nth power and then subract one from the result!

 

And this book is supposed to be teaching me math... ><

Being somebody who has, ironically, a textbook on grammar full of grammar errors and plenty other horrible mistakes in some of his books, I sympathize with you.

Woah. That's happened to me once. Not in an exam though. Woah. Maybe you should teach math.

Just be thankful that you're smart enough to realize the mistakes. :P

Take a picture of that page in your math book. Then edit in the words 'You're doing it Wrong!' Exo will be happy :)

Be glad your math teacher doesn't think the world is flat. Like mine does.

. . . Doesn't it equal 36?

 

:P

 

Thankfully, I can say my math book is just about error free. I'm just happy to be done with it for the term. :P

No one seems to take the job of editing seriously anymore. Mistakes like that are everywhere. Maths Text Books, English Text Books, Dictionaries...

Well that's certainly interesting... I wonder if answering the question correctly on the SATII means you get it wrong. :P

I once had an English teacher who had bad grammar... It's very sad when the 8th grade student knows grammar better than his teacher...

 

Although I've thankfully never run across something of the sort in math. Or this bad. Sheeesh.
