Question

Select a counter-example that makes the conclusion false.

7 - 3 = 4, 8 - 5 = 3, 9 - 8 = 1

Conclusion: the difference of two positive numbers is always positive.

Answer 1

A counter example `meaning false example` would be if the the first positive were greater then the second positive then the number will be a negative.

Answer 2

With that said what is one example?

Answer 3

i dont understand can u try another way im a little slow lol

Answer 4

The examples you are given above are `partially true`.

7 - 3 does equal 4 <---- positive
8 - 5 does equal 3 <--- positive
etc.

But in the examples above the first constant in this case `7` in `7-3` is larger then the second constant `3`. This applies to all examples provided. `8` is greater than `5`.

But what if we switched it around (yet they are still positive)?

Instead of `7-3` what if the second constant `3` is in the place of the first constant? Then the equation would be `3-7` (now they are still positive in this case) but the total is not.

`3 - 7=-4`
`5 - 8 = -3`

Answer 5
