Question

# Use fact patterns to complete each equation.

10 + 9 = 19

9 +.....= 19

- 8
- 9
- 10
7 + 6 = 13
- 7
7 + 6 = 12

Hint:

### Mark the sum on the fact point table and then obtain the augend and the addend.

## The correct answer is: 10

7 + 6 = 13

### >>> We were given that the sum of the augend 10 and the addend 9 to give sum 19.

>>> Similarly, we were asked to find the addend when an augend 9 is added to give sum to 19.

>>> In both cases, the sum remains same and and the augend is decremented by 1 unit. Then, the addend should increment by 1 unit.

>>> Therefore, the sum becomes :

9 + 10 = 19

10 + 9 = 19

9 +10 = 19
