7-18=+=__

1 answer:

8 0

7-18= a negative number. We know that it'll equal a negative number because the minued(7) is less than the subtrahend(18), which results in a negative number (if both are positive).

We can make an addition problem from this. We can have 18 turn negative and 7 stay positive, and we'll get the same answer.

7+-18=7-18

7-18=7+-18=11
