The module then delves into Quotations and Constants, in two parts, where you’ll learn how to work with literal values and constants in Scheme. You’ll also study Equivalence and Predicates, spread across several parts, understanding how to compare values and use predicates for decision-making.

Finally, you’ll explore Boolean Objects and Pairs, Other Predicates, and various List and Pair Procedures in multiple parts, learning how to manipulate lists and pairs effectively.

Section 4: Scheme Programming Series (Module #4) – Numbers, Bitwise, and Strings

You’ll start with Bitwise Procedures, learning how to perform bitwise operations, covered in multiple parts. Next, you’ll explore Byte-Vectors, Characters, and various Number Procedures, spread across several lectures, teaching you how to handle different types of numerical and character data.

The module then delves into Inexact Real Numbers, Fixnums, and various Other Real Procedures, enhancing your understanding of numerical computations in Scheme. You’ll also study Sine, Cos, and Tan Procedures, learning how to perform trigonometric operations.

Finally, you’ll explore Strings and Vectors, covered in multiple parts, learning how to manipulate strings and vectors effectively.
