Learn what a ‘logarithm’ is, what the ‘log’ key on your calculator does, and how to determine and estimate base-10, or common, logarithms.
See the rest of my videos covering other Exponential and Logarithmic Expressions and Equations concepts:    • ★ Exponential & Logarithmic Expressio...  

Corresponds to chapter 8, section 8.1 in McGraw-Hill's Pre-Calculus 12, but also fits with the exponents and logarithms unit from almost any other Pre-Calculus course or textbook.

My instructional approach emphasizes conceptual understanding of and connections between concepts and ideas, rather than just pure memorization.
