Yeah I knew I was trying to choose which ones to post.

Yes! Do you know how to do spoilers?

You can also put them in details

Thanks! I had seen people taking about it on hopscotch so I decided to try it out!

Nice topic!

Unfortunately, I'm just a sixth grader...

We just had variables :P

There's a thing called Breakout EDU, and you have to break the locks solving clues and puzzles. Here are some links to some games, but you can look it up and find more puzzles to do.

Here is an easy math puzzle:

ODD + ODD = EVEN

O = ?

D = ?

E = ?

V = ?

N = ?

Find the values of O, D, E, V, and E. All the variables are different numbers. The numbers are not multiplied but put together to make a three/four digit number.

@Petrichor @FearlessPhoenix Sorry if I didn't make the puzzle clear. If O = 1 and D = 2 (this is not the answer), then ODD = 122.

Remeber to put your answers in [spoiler][/spoiler] tags! Have fun

I can't get it..... I tried literally every combination from o=5 d=0 yet I can't find anything. But that's assuming they can only be singl digit numbers?

**FearlessPhoenix**#276

What equation did you use? I'll assume you started out with 2o+4d=2e+n+v, in some form...

**Petrichor**#278

It's easy when you're not spelling 'ood'

O = 6 D = 5 E = 1 V = 3 N = 0

**MR.GAM3R**#279

Nicely done. There are actually TWO solutions (both are pretty similar), can you find them both?

**t1_hopscotch**#281

That was what I first got too @Petrichor

## I have a question

with that solution, does it work with values of O from 6 to 9 too? And different resulting values of V.

E.g.

```
655 + 655 = 1310
755 + 755 = 1510 // wait no I just realised... V is the same value as D here
855 + 855 = 1710 // okay found it :)
955 + 955 = 1910 // repeated value again
```

And if D is greater than 5, the value of E is too big to add up to as it will be greater than than 1 (bad explanation, sorry) And O has to be ≥ 5 for ODD to add up to a four digit number.

This was fun to think about
