Hmm, youtube won't let me post them in here, I'm sending you a PM with the answers. Yep thats one of them, I'll also let you know that these two are the only ones.

@Jdog7117 One solution of getting 815 is this:

8x9=72,

72+2=74,

74x11=814,

814+1=815.

[Jdog7117]

Well, I decided to finally write my program to output all answers to a problem. More precisely, it outputs (almost) every syntactical way of writing each solution. So you have to then trim out all the duplicates. So to answer your question about how many solutions, 8. I removed all the different ones that were basically different ways of rearranging the same mathmatical statement, or at least my opinion of what was different. For Example to me, (9-8) + 10 + 6 is the same as 8+9

@cwn89015 I don't know, my program only gives me one, i would have to change it to return multiple solutions. Sometimes (as in the one you just asked about) I can fiddle with things like the order I enter the numbers into the program. That causes it to find one solution before it finds a different solution, so I can find out more than 1.

That problem has at least 2 different ways of doing it. Once again I'll let you try to solve it. Let me know if you need hints :).

@Jdog7117 Also, on Wednesday May 20th, 2009, Part 4 of 4, is 815 possible?

[cwn89015]

@Jdog7117 5 solutions. Is that all of them?

[Jdog7117]

@cwn89015 That was it. Well done!

[cwn89015]

@Jdog7117 I hope this is it:

6x8=48,

48x10=480,

50x9=450,

480+450=930,

930+5=935.

Took me a while, but it happened. Was I right?

[cwn89015]

@Jdog7117 I'm working on it, but another one I fiound is this:

9x6=54,

54x10=540,

50x8=400,

540+400=940,

940-5=935.
