I'm bad a math someone help, I have to hand in this assignment to my grade 2 teacher tomorrow.

EDIT: I got it wrong and got detention, you guys suck.

2+1=4 silly

Now go do the equation yourself before I tell on you

2+1 can be anything but 3

Did you seriously take this seriously?

unless this has some sort of geometrical catch, your question is not solvable, because we don't know how 2 and 1 relate to each other within your system. And even if we knew, the solution would probably too be arbitrarily redefined by you.

definitely 8

so 2^2 is 5, 2=5^(1/2), which is 2.23606798. If 1^2 is 11, then the same principle applies, making 1 equal to 11^(1/2), or 3.31662479036. If we add these two, we get 5.55269277036.

tl;dr 2 + 1 = 5.55269277036

so 2 = 2.23606798 ?

why would you even bother going though with that procedure after you got something like that. You can't just apply the commonly accepted system to his. It's like trying to binary code in hexadecimal, throwing letters at my computer to see what he makes with them.

you're going completely wrong here, 2+2=/=2^2 and 1+1=/=1^2 so your whole calculation is useless.

yes, 2=2.23606798, that was the entire point of the equations

you mean x^x ≠ x+x

because 2+2 kinda is the same as 2^2 and 1+1 also kinda is the same as 1^2

thats fine, but you got to that conclusion applying the standard system to his, which is not possible.

well 2+2 happens to be the same as 2^2 in our normal field, but 1+1 is definitely not the same as 1^2
also if 2^2=5 then 5^(1/2) would be 2 and not 2.2something.
Railey2
oh lol 1+1 is 2

*sound of glass shattering*

if theres something like an arch-mistake, then I just made it.

you are guilty too though, with saying that 2+2 ≠ 2^2
:p
silmarilen
yeah true, i was thinking too much so i missed that obvious part :P
Railey2
ok, to make this clear,

this is our normal decimal system

this is OP's system



If 2+2=5 and 1+1=11 what's 2+1

"2+2=5" and "1+1=11" is absolutely not our normal decimal system, because
2+2≠5 and 1+1≠11
thats why I use the different color.




what you suggest, is
2^2 is 5, 2=5^(1/2), which is 2.23606798 ... and so on.
This is not possible, its a mixup.

@silmarilen, I thought of a better riddle, try to solve this:

4+4 = 7
4^4 = 7
4/4 = 3
3*3 = 3
3/3 = 3
3+3 = ?

4+4 = 7
4^4 = 7
4/4 = 3
3*3 = 3
3/3 = 3
3+3 = ?
x = 4
y = 3
x+x = x^x = 7
x/x = y*y = y/y = 3
y+y = ?

y*y = y/y this logic suggests that * and / are one and the same operation
x+x = x^x also suggests that + and ^ are the same operations

x^x = 7, 7^0.25 = 1.6265765617
so x = 1.6265765617
the only way for 1.6265765617 to become 7 is 1.6265765617^4 and considering x+x = x^x the real identity of + is ^.

Now I'm gonna go by the ruling that when + or ^ is used the second operand becomes seperate from the value of x or y cus' fuck it.
e.g. the real expression for 4+4 = 7 is x^4 = 7 but for x/x = 3 it is still x/x.
Now:
x/x = y*y = y/y = 3
1.6265765617*1.6265765617 = 2.6457513111 but we can just round that to 3.
so / is actually *.
y*y = 3 is the same as y^2 = 3
3^0.5 = 1.7320508076
y = 1.7320508076
y+y = y^3
y^3 = 1.7320508076^3 = 5.1961524227
Since I appear to have made it a rule previously that all answers must be rounded to integers the answer must therefore be 5.
TLDR 3+3 = 5

congratz silmarilen

EneT, far off.

Fuck sake.

explanation:
3, 4 and 7 are actually numbers written in a different way. forget their actual meaning as you know it
now, +, ^. * and / still have their original meaning
so now look at it
4+4 and 4^4 have the same answer, that only happens with 2, so 4=2
3*3=3, 3/3=3 this only happens with 1, so 3=1
now 3+3 is actually 1+1, which is 2. and in our new system 4=2 so 1+1=2 becomes 3+3=4
Railey2
I just included the operations with / to exclude 0
silmarilen
yeah i realised after i made the post that 3/3=3 wasnt necessary to know the answer but i hadnt thought about them being there to rule out 0 yet.
Railey2
theoretically, you could still find a different solution by treating the operators as the part that changed, but that sort of fails Occam's Razor. Or you just redefine everything and create something crazy.

But yes, the way you solved it was the way it was meant to be solved.
silmarilen
occam's razor is love, occam's razor is life.
Railey2
now that I think of it, the lazy way would be to redefine + as "equal to ^, yielding 7 as a result when used between 2 arbitrary numbers"


then define / as always yielding 3, and * as equal to /


the result of 3+3 is 7.

But thats kinda cheating, is it not?


or you just define ? as always being an orange cube. The only challenge would be not creating a contradiction.
