Students perform operations with matrices. In this algebra lesson, students use cryptography and cryptanalysis to solve problems. They add, subtract, and multiply matrices.

Young scholars relate Cryptography to the solving of simultaneous linear equations in matrix notation. They explore various methods of encrypting and decrypting codes. Pupils discuss and solve simultaneous linear equations.

High schoolers explore the history of cryptography. They assess function notation and transformation, matrix operations, and the fundamentals of modular arithmetic. Using graphing calculators, students develop their own encryption...

Students explore cryptology. They write a research paper on cryptography. Using linear equations, students invent a code and write a secret message. Students complete cryptography puzzles.

Young scholars differentiate the types of cryptosystems and use them to communicate privately. In this algebra instructional activity, students use substitution and transposition to identify the cryptographs. They send and receive...
