Unit-V: Mathematical Reasoning
1. Mathematical Reasoning
Mathematically acceptable statements. Connecting words/ phrases – consolidating the
understanding of “if and only if (necessary and sufficient) condition”, “implies”, “and/or”, “implied
by”, “and”, “or”, “there exists” and their use through variety of examples related to real life and
