Whats 2+2 i'm really confused about this i literally dont know what 2+2 is i said 5 in class but i was wrong

Put 2 fingers out and then pull 2 fingers out of your other hand. How many fingers do you have?

I’m going to guess these are the choices: a) recreational skiing developed in the mid-19th century b) it was originally invented as a way of getting from place to place in snowy regions c) downhill skiing is currently the only common form of the sport d) it mostly evolved from snowshoeing- if that’s the cases then the answer would be c) downhill skiing is currently the only common form of the sport
