I'd like one of the younger children to answer iwilli28's question

Explain how you can solve 40 x 16 by breaking apart the numbers.

How about 4 x 10 x16 = 4 x 16 x 10 = 64 x 10 = 640

How do you make 25+35
with just the numbers 5, 5 and 7 ?
Hint: factorise out 5.

25+35=(5+7)*5=12*5 (which isn't really any easier than 25+35 which you can easily make 30+30, but hey...) = 60

I was promised cake, where is it?!

So, I guess I post the next one?

Hum...
5+6=218

It wasn't meant to be easier, I just want people to play with numbers

What cake, what question, I'm all confused. 5+6=218 ? What mystery does this hold ?

Playing with numbers?
Now that's just irresponsible!


The mystery to the very answer of that riddle! :3

5+6=218

5+6= 3+2+ 2* 3
.......(3+2+2)* 3 .........=21
...........(2+2* 3)..........=....8
.................................=218

therefore 5+6=218 and 3 is the key to the universe

That looks pretty nifty. :3

But actually is the checksum of 218 = 5+6 = 11
