## 5 25 325 4325

Given

1 = 5

2 = 25

3 = 325

4 = 4325

What does 5 equal?

54325. Rather than being a mathematical solution, the answer is derived by prepending (putting in front of) the value on the left side of the equation with the previous answer. So for 3 you take 25, the previous answer, and put 3 in front, giving you 325. Then you put 4 in front to get 4325 and lastly, put 5 in front to get 54325.

Surely 5 would equal 1 as we have already seen 1 equals 5

That assumes a symmetric relation which is true in normal math, but not safe to assume when 2 = 25.

By this logic, 1should be = to 15

What logic is that?

*before I look at the answer

I took geometry last tear and by that logic it would equal 1.

by peoples riddle logic it would be 54325.

*after I looked at the answer

peoples riddle logic amazes me…. how did I get that right?!?!?!?

Guys, when answering a riddle, don’t assume normal mathematical principles are being used.

I also agreed that 5=1

If 3===> 540

4 ===> 1280

6 ===> 4320

Then:

10 ===> ???

Any ideas ??
