Answer:
6 + 7 = 13
Step-by-step explanation:
We are given the following information in the question:
We know that
[tex]6 + 6 = 12[/tex]
We need this information to evaluate
[tex]6+7[/tex]
The evaluation can be done with the help of using associative property and distributive property.
Associative property: (a + b) + c = a + (b + c)
The evaluation can be shown as:
[tex]6 + 7\\= 6 + 6 + 1\\=(6 + 6) + 1\\= 12 + 1\\=13[/tex]
