Can you guys do me a favor?

[flamepony12]

If you have time, will you tell me if this magic number trick works for you?
make sure you have a calculator if you're going to try it..
thanks

-Pick a number between 1 and 10.
-add 3.
-double it.
-take away 5.
-add 7.
-subtract 4.
-multiply by 10.
-divide by 20.
-take away 7.
-give back 10.
-take away 3 more.

(edit: thanks William!)
Whatever you come out with *should* be your original number plus 2.

Sorry, didn't work.

starting with 3 yields 5, 2 yields 4

(this is Devon, by the way)

hmm. it seems to vary depending on the kind of calculator you use. if you try it on the type that solves after every two numbers you type, it usually doesnt work.. but if you use a calculator which waits until you're finished with the whole equation to solve it, it does.. I'm pretty sure it works when you solve it algebraically, so.. I guess I'll wait for a couple more responses and see how it worked out for others and then see what I did wrong-- thanks for trying it out

(on the two calculators I tried it on, 5 yields 11 and 2 yields 8)

OMG! IT'S MATH! MATH! MATHHHHH!!!

*Runs away and shoves head in the dirt*

[k9krazee]

No..it didn't work for me.

[BC_MoM]

Didn't work for me either - I chose 7 and had 9 in the end.

[Vette]

OMG! IT'S MATH! MATH! MATHHHHH!!!

We must be related

[buttercup132]

Didnt work for me either. I though I would wait till other people replied first so I didnt feel stupid for being the only one who didnt get it

I started with 9 and ended up with 4 lol

[Pawsitive Thinking]

Started with 4 ended with 6

[Donnaj4962]

Didn't work for me either.... I started with 9 and ended up with 11!

I hesitated to even do it, since me and math are not compatible in any way, shape, or form. But when I saw that I could use a calculator, I decided to give it a try. I even did it 2X.

[Karen]

Nope, started with 6, ended up with 8.

Nope sorry came up with 9 and started with 7 oh oh never mind try it again later maybe get my husband to try it and drive him insane love doing that

[buckner]

Nope, didn't work. I plugged in 8 and got 10.

[flamepony12]

That's so weird! haha. We've tried it on four different calculators and it's worked. oh well, Start over! xD; It's for a small part of this project that we have to do for the math I'm taking.

[vinjashira]

I quite like Math actually
using your algorithm you should end up with your original number plus two, not six

Let's say your original number is x

-add 3.
x + 3

-double it.
2x + 6

-take away 5.
2x + 1

-add 7.
2x + 8

-subtract 4.
2x + 4

-multiply by 10.
20x + 40

-divide by 20.
x + 2

-take away 7.
x - 5

-give back 10.
x + 5

-take away 3 more.
x + 2
