§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!

Slide 2 - Slide



Do you remember the signs:
           for 'smaller than'       and 
           for 'greater than'?
