Beginner Topic 3 of 51 Math for Computing

Exponents and Logarithms

Powers and their inverses, central to complexity.

How it works

log_b x asks "what power of b gives x"; log laws turn products into sums, and log₂ n counts halvings (binary search steps) and tree height.

Where it is used

Complexity analysis, decibels, entropy.

Common pitfall

log(a+b) ≠ log a + log b.

Where it fits in the course

Exponents and Logarithms is topic 3 of 51 in Math for Computing, rated Beginner. It follows Algebra Review. The next topic is Summations and Series.
