OT: Can you solve this ostensibly simple 2nd grade math problem?

Poor monkey!! It doesn’t understand the independence of falling and forward motion.

As I tell my 6 year old daughter, there is no guessing in math. You take your time and you work out the problem.
I actually thought about adding a second equation with y, and then explicitly stating the definitions for the variables, but it was time for breakfast.

It's a trick question: Dogs can't sign up since they can't write. Only humans can sign them up to compete.
There really isn't anything wrong with this problem. However it isn't second grade -- more like fifth grade math in the US - probably kindergarten math in China or India!
S = # of small dogs
L = # of large dogs
S + L = 49
S - L = 36
Adding the equations together, the L's cancel, and get 2S = 85
Divide each side of the equation by 2 and get S = 42.5 small dogs. L = 6.5 large dogs.
Check: Sum is 49; difference is 36.
That's it. It isn't a hard problem. The answer is silly since it results in a half dog. The author of the problem should have specified 50 as the total number of dogs in order to get a whole dog solution.

What the hell are you talking about? The answer is 42.5 small dogs, 6.5 big dogs. Are you saying that makes logical sense? Or are you saying it's possible to have a dog that is half small and half big?
There is so much "goodness" in this post that I don't know where to begin.
I guess with "Not sure if serious."
Dude, are you by chance doing your math thing for NASA? At "lease" you showed your work.
Finally, the answer reveals itself!
It must have been this Pit Bull...
... and Dachsund mix...
...was entered in the contest as 1/2 a big dog and 1/2 a small dog.

The mental image of this dog's conception is disturbing. Recalls that episode of South Park when Chef hooked up a male elephant and a female pig (i.e., a sow). Wonder if they had Barry White playing in the background while it all went down...
..This is turning into this legendary thread...

First i come here once a day. If i am wrong show me in mathematical terms (it is called a proof). My revision is not a rewording of the original problem.
The proof is a couple posts above you. (Lemon ears) You are answering what they probably meant to ask, not what they actually did ask. Throw your arrogance (ignorance) away, re-Read the question better and look at the proof above.
It's really a betting line word problem, prepping the kiddies for future Vegas trips. Brilliance by those peeps at Caesar's who dreamed up the word problem!
Team A is favored by 36 and the Over/Under is 49.
The people setting the line expect Team A to win by 42.5 - 6.5, give or take the half point. In reality, they would likely add the half point to the spread and/or to the O/U, but since we are talking 2nd graders here just learning how to read these betting lines, they went with whole numbers in the question.
The tipoff is they use "dogs" as the object to be counted, getting the "underdog" phrasing ingrained early and often.
In 3rd grade they start easing them into some simple prop bets. "Will Mrs. Johnson give a surprise spelling quiz next week? What day of the week will she give the surprise spelling test? Morning or Afternoon? If there are 20 spelling words on the test, and you get 12 more correct than Bob78, how many words did Bob78 misspell?"
No child left behind, even if they cannot legally step into the casino.

Real numbers (decimals) are not introduced in Second Grade Mathematics. Therefore, give me an answer with integers (whole numbers); FYI no rounding is allowed since real numbers are not introduced until much higher grade. Lemon Ears ???, Arrogance - As Carly Simon sang " You're so vain ..."
when or how real numbers (decimals) are introduced is not relevant to the problem. You got it wrong, so what? Just own it, and stop digging, and say as much.
Because lets face it, your answer was so wrong it wasn't even close. Had you rounded the correct answer off and justified it by saying you can't have half a dog, you may have been able to justify it with the above.
I just realized something (on occasion, I am slow). In my 7+ years on the board, I don't recall anyone ever using the word ostensibly in a thread title. I have not given one of these out in quite a while, but .......
Congratulations LafayetteBear! You have won the "fairgambit word of the week" award. Well done!
Gambit: LOL, I am gratified to receive your commendation. I'll try not to let it go to my head, and am sure that I'll receive some help in that regard from my friends over on the Test Board..I just realized something (on occasion, I am slow).

I don't know if anyone else took the time to click on the above link and check out that thread, but it's frickin' hilarious. Props, CLion.
Whoa. I had to look that one up. Sadly Gambit only gives one award a week so you will have to settle for the satisfaction of knowing you increased my vocabulary.

I suddenly feel a lot better about this board after reading that...
That thread is hilarious. Seems to suggest we are not ranked very high among nations in mathematics. Let's say we're ranked 27th, but tied with another nation that is also ranked 27th. Does that mean we are ranked 27.5? Is that even possible?
Sort of, but in a non-apples-to-apples example:
I believe that in professional golf, if two players are tied for 3rd, they combine the 3rd and 4th place money and split it evenly (so like finishing at 3.5 instead of either 3rd or 4th). If three are tied, they combine the 3rd, 4th, and 5th place money and split it evenly. And so on.
If that has changed at some point, someone here will let us know.
If that's legitimately a math problem for second graders these days, then we definitely aren't falling behind other countries in math.
