Look at the table to find that when 2 is put in, 3 is pulled out.
3

The number that is pulled out is 1 less than 2 times the number that is put
in. When 3 is put in, the number that is pulled out is 3^2-1=5.

When 2 is put in, 3 is pulled out, and when 3 is put in, 5 is pulled out.
5

Problem solving

1 The sum of the two numbers that are connected by a line is always 10.

Since 5+ =10, =5.
The product of the two numbers that are connected by a line is always 24.
Since 12^ =24, =2.

2 When the parrot says “cliudy,” he means “cloudy,” so he mixes up the vowels

“i” and “o.” Switch all the is to os and os to is.
“Today it is very cloudy outside.”
