§9.4 Solving inequalities

(ongelijkheden)

Up to now we only dealt with equations, like:                  'something 'something being equal to something else'.

However,  

something can also be greater than or smaller than                        something else!

Do you remember the signs:

           for 'smaller than'       and 

           for 'greater than'?
