Question

Type a counter example that would have to exist in order for the conclusion to be false.5>0,6> 0.12 > 0,16 > 0,20 > 0,100 > 0.Conclusion: All numbers are greater than 0.Counterexample: ?

Answer 1

Here, we want to give a counter example which would exist to make the conclusion wrong.

To do this, we have to get the values which are in actual terms lesser in value to zero. These values include the negative integers i.e negative whole numbers. On the number line, these values exist before zero, to the left handside of the number line.

Examples of these values include -5, -4 , -3 , -2 etc

So the counter example can be in the form;

-3 < 0 , -5 < 0 , -2 < 0

With these set of examples, we have made the conclusion false.
