Been busy the past few months. I know this is a bit late, but happy new year to all.<img src="http://feeds.feedburner.com/~r/proofsfromthebook/~4/KMxJXldJa2s" height="1" width="1" alt=""/>http://proofsfromthebook.com/2017/01/24/busy-last-months/feed/0http://proofsfromthebook.com/2017/01/24/busy-last-months/Negation and the Not Connector

We learned that compound proposition is a proposition formed from simple propositions using some logical connectors. The first logical connector that we are going learn is about “not” which is used … <a href="http://proofsfromthebook.com/2016/10/25/negation-not-connector/">Continue reading <span class="meta-nav">→</span></a><img src="http://feeds.feedburner.com/~r/proofsfromthebook/~4/Cy_oDQVd5sQ" height="1" width="1" alt=""/>http://proofsfromthebook.com/2016/10/25/negation-not-connector/feed/0http://proofsfromthebook.com/2016/10/25/negation-not-connector/Introduction to Compound Propositions

We learned that propositions are statements that are either true or false but not both.

We will start this journey by learning about propositions. In our daily lives, we often encounter statements that are either … <a href="http://proofsfromthebook.com/2016/08/28/understanding-propositions/">Continue reading <span class="meta-nav">→</span></a><img src="http://feeds.feedburner.com/~r/proofsfromthebook/~4/u_XgCG8nS-g" height="1" width="1" alt=""/>http://proofsfromthebook.com/2016/08/28/understanding-propositions/feed/0http://proofsfromthebook.com/2016/08/28/understanding-propositions/A reboot for Proofs from the Book

We will be studying formal proofs starting with logic (truth tables, logical connectives, etc.) and then study different methods of proofs (direct, indirect, etc). While studying these concepts, we will … <a href="http://proofsfromthebook.com/2016/08/07/reboot-proofs-book/">Continue reading <span class="meta-nav">→</span></a><img src="http://feeds.feedburner.com/~r/proofsfromthebook/~4/Mbi91HBGlk4" height="1" width="1" alt=""/>http://proofsfromthebook.com/2016/08/07/reboot-proofs-book/feed/0http://proofsfromthebook.com/2016/08/07/reboot-proofs-book/Understanding If-Then Statements Part 1

If-then statements are used often in mathematical proofs as well as real-life conversations.
