Hi tina123!

Look at the number line:

... -3 -2 -1 0 1 2 3 ...

_____.___.___.___.___.___.___.___

To the left means smaller or less than.

Since -2 is to the left of -1, then -2<-1.

More generally

...-3<-2<-1<0<1<2<3...

You'll get it!

Writing "pretty" math (two dimensional) is easier to read and grasp than LaTex (one dimensional).

LaTex is like painting on many strips of paper and then stacking them to see what picture they make.
