Hello Ms. Sue that makes sense so -197 is less than -110?

*December 6, 2016*

**Math**

Or do you mean the greater the negative number the less it is regarding the number in front of it?

*December 6, 2016*

**Math**

Hello Mr. Bobpursley and Ms. Sue are you saying that when -197 is on the number line on the negative side that it would be always less than a number that is before the number -197? Please advise.
