Starting a Proof for Show 4 < 5

Click For Summary
SUMMARY

The discussion focuses on the mathematical proof for the inequality "4 < 5". Participants emphasize the importance of defining the numbers involved and the less-than symbol. A suggested approach includes proving the foundational inequality "1 > 0" and demonstrating that adding the same value to both sides of an inequality preserves its truth. This method establishes a clear pathway to validate the original statement.

PREREQUISITES

How do you start a proof for "Show 4 < 5"?
 
Physics news on Phys.org
State the definitions of 4, 5 and <.
 
I would start by proving 1 > 0, and then prove that if you add the same number to both sides of the inequality, it remains true.
