Someone sent me one of those “Are You Smarter Than a Fifth Grader?” puzzles yesterday. Thankfully I was. I thought I would do my own skill testing question contest here on the blog, just to spice things up a bit.

The “Rules” are simple:

1. You must submit your guess/answer as a comment.

2. All entries must be received NO LATER than 12 pm Haiti time (that’s 9 am Pacific) TOMORROW, February 1st, 2008.

3. The first comment received with the right answer wins.

4. You must include your name in the comment somehow so you can be identified.

The Grand Prize you ask?

Well, full out blog bragging rights of course!

Okay, now for the amazing skill testing question…

724 x 2 – 1253 x 2 -6

Okay, get your guesses in! You don’t want to miss the big reveal tomorrow. It’s all about blogger craziness over here in Rolling Land! LOL!

**÷**

128 = ?

Have fun and see you tomorrow!

tara’s answer —3

(724 x 2) – (1253 x 2) – (6 / 128) = -1058.04688 724 times 2 = 14481253 times 2 = 25061448 minus 1253 = negative 10586 divided by 128 = .0468negative 1058 minus .0468 = negative 1058.0468Vicki

Too bad you don’t have calculators in Haiti ;-)THe answer according to my trusty Texas Instrument is —– 3!

I get 3Kelly

Submitted by Barb J on behalf of Paul J. 724 x 2 – 1253 x 2 -6÷128 = ?The incorrect answer, obtained by just doing the operations in sequence is 3.However, the rule of order of operations states that multiplication and division take precedence over addition and subtraction, and a horizontal fraction line is considered a form of grouping, which means operations on either side of it are done separately.The problem with this formatting is that it leaves the intent vague. Because the division sign is on a separate line, this implies that it is to be interpreted as a horizontal fraction line. This would mean all the operations above the line are done first, which would produce -1064, then divided by 128, producing -8.3125.If that wasn’t the intent, then the order of operation rule applies to 6 divided by 128, and the answer is -1058.046875.Me, at this point I have no idea.Barb J :)

the answer is 3. you can send my prize to…..on second thought, just hold it and I will come down and pick it up. we just had 10 inches of snow in the St. Louis area and Haiti is sounding pretty good now. :)

Leslie, you’re cheating!!! I have put this in 3 x’s now and your site won’t let me in. I demand an investigation!!!!! :) the answer is 3. I will come down and avoid the snow in St. Louis, 10 inches last night. Haiti is sounding good now.
