What are shorthand operators and how do they provide a more efficient way to update variables?
Shorthand operators, also known as compound assignment operators, are a feature in PHP that provide a more efficient way to update variables. They combine an arithmetic or bitwise operation with an assignment operation into a single statement, reducing the amount of code needed to perform the operation. In PHP, there are several shorthand operators available

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
