Explain the order of operations in mathematical calculations using BIDMAS.
The order of operations in mathematical calculations is a fundamental concept that ensures consistency and accuracy in computations. BIDMAS is an acronym that stands for Brackets, Indices, Division and Multiplication, Addition and Subtraction. It serves as a mnemonic device to remember the sequence in which mathematical operations should be performed. Brackets are the first priority

How are addition and subtraction operations performed in Galois Fields?
In the field of classical cryptography, specifically in the context of the AES block cipher cryptosystem, Galois Fields (also known as finite fields) play a crucial role in performing addition and subtraction operations. Galois Fields are mathematical structures that are used to define the arithmetic operations within AES, providing a foundation for its cryptographic operations.
