Wicked 3rd grade math problem.

[Lamar]

And....... I still don't get it.

 

[Rockminer]

And....... I still don't get it.

You're not the only one.....

I must still be missing something here. Where do I place the grids?

 

[TheVez2]

The grid is separate from the equations. Just draw a grid and number it as described. The value of the symbol comes from the shape that the number occupies in the grid. So, again, with the corrected symbol in the middle you get:

1+2=3
4+1=5
6+2=8

 

[cb91710]

2+3=5
3+2=5
3+3=6

*crosees fingers n toes its all correct*

Not if the symbols represent the same values and each value is only represented by one symbol.

Gotta be it.

How do we know that ] is 4 and [ is 6?

 

[Rockminer]

So the answer is 1+2=3 ? The other lines were clues and we are assuming that second symbol, on the second row, is not correct.

 

[lowcountry_sc]

yes

 

[Lamar]

I'm gonna go back to grade school and repeat 3rd grade. I must have been sleeping.

 

[lowcountry_sc]

yes, however large that assumption may be, it still makes the most sense.

 

[Cheese]

Got it. Fun trick.
Palmar, I think there is consensus that the middle symbol, second row is drawn incorrectly. Should be a J.

Ah, thank you sir! The funny thing is, one of the first things I did was replace the symbols in the first line with 1+2=3. But even if the middle symbol had been right, I still didn't have enough to fill out the rest without knowing why they were those numbers.

For extra credit, your son can submit his answer written in PigPen Cipher.

I hope it was the teacher that screwed up on the middle symbol so your kid can correct his butt. My wife is going to kill me for coming to bed so late. Good night all!

This is the key:

See it now?

 

[Lamar]

Well I was just responding to rockminer in a PM about how it could be something else..... BUT now I see it! I have seen the light! Now I can go face my wife and explain to her after I wake her up as I get in bed that it was because of a tic tac toe grid and 9 numbers. She will certainly understand.

BTW, is dpm802 part of Mensa or something?

BTW, is dpm802 part of Mensa or something?

I never got around to officially joining, but yeah, I'm qualified. I've got SAT scores that will get me in without having to take their entrance exam.

But as my avatar once said ... "I'd never join any organization that would have someone like me for a member."

BTW, all I have to do is show those SAT scores plus $2.09 and I'm entitled to a Grande coffee at any Starbucks in America.

 

[5 o'clock shadow]

Those SAT scores worth that much?

When math become something other than numbers, it isn't as much fun...
