For $2 + 10$, the answer is $12$.
For $8 + 9$, the answer is $17$.
For $13 + 5$, the answer is $18$.
For $12 + 7$, the answer is $19$.
For $13 + 1$, the answer is $14$.

Fill in the missing answers
Write the answers next to each corresponding equation:

$2 + 10 = 12$
$8 + 9 = 17$
$13 + 5 = 18$
$12 + 7 = 19$
$13 + 1 = 14$

The completed answers are:

$12$
$17$
$18$
$19$
$14$
