In mathematics is 2=1?

In mathematics is not true 2=1

But  for funny Mathematics I can prove in following way

We know                -1 = -1

we can write         -1/1 = 1/-1 

taking square root both side 

                               sqrt(-1/1) = sqrt 1/-1

we know sqrt (1)= 1  and sqrt (-1)= i , using this we get 

                                                  i/1 = 1/i

divide 2 both side we get           i/2 = 1/2i

adding 3/2i both side we get      i/2 +3/2i = 1/2i+3/2i

multiply i on both side we get  i(i/2 +3/2i) = i (1/2i+3/2i)

                                        (i^(2)/2)+ (3i/2i) = (i/2i) + (3i/2i)

we know  i^(2) = -1 using this above 

                                        (-1/2)+ (3/2) = (1/2) + (3/2)

                                                    (2/2) = (4/2)

                                                          1 = 2

                                            or          2 = 1 

Thus result is proved. 

This for only funny Mathematics not real Mathematics. 

I agree with the answer, Mr. Abdul Basit

No; in mathematics is not true 2=1

But in the life it is possible. 

2=1+(?)

let unknown number is x

2=1+x

x=2-1

x=1

it is possible when the value of x is 1.

No 2 is not equal to 1. Here you find a nice discution:

Apologized for the answer, your question is not clear, and incomprehensible .
