Think of it this way let’s say if your mom gave you $1 but she said I’ll give you another $1 if you finish your chores or something
So now u have $1 plus the other $1 she gave you
1 + 1 = 2
You don’t want one dollar you would rather have 2 dollars
If that doesn’t help just count from 1 - 10 and what comes after 1 it’s 2, then 3, then 4, then 5, and so on ….
Answer is 2
