In order to solve it you must make each component negative. Multiply them by negative one!
M < 2
Now which numbers would satisfy it? M is less than two... so, m could be one, or any negative number, yeah?
Multiply by negative one. - M and -2 are what you have. If it were one... negative one is less than negative two. Turns out M is less than two.
M < 6
M is less than six. It could be 1, 2, 3, 4, or 5.
-M and -6
Is negative 3 less than -6? All of the numbers are! So, m is actually less than 6
