Mr carter wrote a double fact, it has a sum greater than 6 the addends are each less than 6, what fact might he have written?

He might've written 5+5, here's why:
The question is asking for 2 numbers that are less than 6 and add up to be more than 6

Number 1 < 6, and Number 2 < 6. Number 1 + Number 2 > 6
