##### QUESTION 3

Let’s play a game called target number. Here’s how it works. I give you a target number and starting number and you tell me what I need to get there.

For example, our target number is $20$20, and if I tell you the number $19$19 you would say $1$1, because $19+1=20$19+1=20.

Find the missing number below for our target number $20$20.

1. $18+\editable{}=20$18+=20

2. $13+\editable{}=20$13+=20
