Nice guide. Looking through it I noticed the following:

Quote:

Special Properties of Exponential Expressions Involving 1 or 0 1^n = 1 x^0 = 1 (Exception: 0^0 = Undefined) 0^n = 0 (Exception 0^0 = Undefined)

Should the exception for 0^n read "0^n is undefined when n is less than or equal to zero)? I would think 0^-1 = 1/0 = undefined (can't divide by zero)

I tried googling but couldn't find an answer.

Yes, 0^x is undefined when x is negative, not that a real GMAT question would ever allow for that possibility.

Wonderful stuff Slingfox. I had a question about your Quant review...I remember doing this problem before but cannot seem to figure it out now. Can you please explain this, preferably with a more complicated example? Thanks.. Ratio problem/locate a point on a line segment: o Coordinate A is at (0,0) and coordinate B is at (4,4). Find the point that is 3 times away from B as A on line segment AB. Approach: You need to find dx which is the incremental change in X, and dy which is the incremental change in Y. Total change in x = 4 = 4dx o =1 Total change in y = 4 =4dy o dy = 1 Answer: (0 + 1*dx, 0 + 1*dy) = (1,1)

Great Stuff...thanz a ton for the details...just a quesry...

the statement Example: S/T = 64.12. Which of the following could be a remainder when S is divided by T? 2, 4, 8, 12, 20, 45. Answer. 12/100 = 3/25. This means that when S is divided by T, the remainder must be a multiple of 3. Therefore, 45 is the answer.

i believe the answer should be 12.if you divide 12 by 100,it clearly leaves 12...
