The sum of a number and four is less than twelve
Anettt [7]

Answer:

Some answers would be 7 6 5 4 3 2 1. Not all numbers will be less than twelve.

Step-by-step explanation:

First, I added the number to 4 that would equal twelve. Then, I just started using numbers below it. If this is a true or false, this would be false because if you added any number (let's say 12) to 4, you might get more than 12. Although, every number in the negatives would work as well, because they didn't state that the absolute value of the number plus 4 is less than 12. Hope it is right!
