What number, when multiplied by itself, has the same answer when it is added to itself?

Question

What number when added to itself, subtracted from itself, multiplied by itself and divided by itself, will add up to 22.09?

Answer 1

2*2=4
2+2=4
So 2 must be an answer.
but
0*0=0
0+0=0
So 0 also be one of the answer.

Answer 2

THE SOLUTIONS ARE;
1) 2+2=4
2*2=4
2)0+0=0
0*0=0
3) IT CONSIST OF AN IMAGINARY PART. SINCE IT IS NOT MENTIONED ABOUT REAL OR IMAGINARY NUMBER

2(i)^(4n) + 2(I)^(4n)=4(I)^(4n)=4
2(I)^(4n)*2(I)^(4n)=4(I)^(8n)=4
THE ANSWERS ARE 2,0,2(i)^(4n)

Answer 3

2 x 2 = 4
2 + 2 = 4

Answer 4

Supposed that, the number is n.
According to the condition,
n*n = n+n
⇒ n² = 2n
⇒ n²-2n = 0
⇒ n(n-2) = 0
So, n=0
Or, n-2 = 0 ⇒n=2

Answer 5

Ans 2
2+2 = 4
2*2 = 4

Answer 6

2*2=4
2+2=4
hence ans is 2

Answer 7

let no=a
then aa =a+a
a*2 =2a
solving,a=2 answer
