**What Is 1 1**

### Puzzle / Hint: What is 1 + 1?

I do not know. I did not go to university.

1 + 1 = 1 + 1

Eleven

Two options:

1 + 1 = 10 in amount

1 + 1 is for a child if it is male and female

1 + 1 = window

1 + 1 = 10 (2 inches)

1 + 1 = 1 + 1

1 + 1 = [(1 + 1) 1] / 1

1 + 1 = t

1 + 1 = 1 (try below)

x = y

x2 = xy

x 2 y 2 = x 2 xy

(x + y) (x y) = x (x y)

x + y = x

1 + 1 = 2

2 = 1

1 + 1 = 0
