Answer:

m-9

-9+m

Step-by-step explanation:

m-9

The one way is the way it is given in the problem m minus nine

However it can also be written by interchanging the position of each term , but while interchanging we have to carry their sign along with them also.

Hence m can be taken on the left but with its + sign

and 9 can be taken in the right but with its sign that is -

Hence

m-9 can also be written as

-9+m
