Addition

J: Mommy, how long do I have to go to school?

Me: Well, people normally go to school until they're about 18.

J: Oh.

Me: How old are you now?

J: 4.

Me: So how long do you still have until you're 18?

J: 44?

Funny! :)

Show them this. it should clear things up.


a = current age
b = age at future event
c = years until future event

b - a = c

or

b + -a = c
