Why does 2+2=Fish?

Why does 2+2=Fish

Because if you take the first number and flip the second number backwards and stack them, they look like a fish, an 8 and a triangle.

It’s really easy. When you combine/flip the numbers together, you get that shape or object.
1 + 1 = Arrow
2 + 2 = fish
3 + 3 = 8
4 + 4 = ???
5 + 5 = Headless fat guy
6 + 6 = Butt
7 + 7 = Triangle
8 + 8 = 8
9 + 9 = Butt
10 + 10 = 1010

Combine numbers as objectives not calculations and you will get these shapes.

Just put one of the numbers like in a mirrror then they together make a picture of the word.
