“So what does 2 + 2 equal?”
Luckily, that one’s pretty straightforward.
If you take 2 and add 8 to it you get 10. If you take the other 2 and add 8 to it you get another ten. Then if you combine those tens you get 20. Now you had to add two extra “8’s” to get that 20, so you’ll have to remove them now - but you have to do things in tens, so make each “8” a ten, and subtract those two 10’s from 20 and you’ll first get 10, then zero. BUT since the tens you subtracted from the 20 are 2 more than the “8” you actually had before, you have to add to that zero first a 2 (which gives you “2”), then another 2, which gives you “4”.
