FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Detailed explanation-2: -A. Parentheses are the first operation to solve in an equation. If there are no parentheses, then move through the order of operations (PEMDAS) until you find an operation you do have and start there.

Detailed explanation-3: -In other words, in any math problem you must start by calculating the parentheses first, then the exponents, then multiplication and division, then addition and subtraction.

Detailed explanation-4: -The standard mathematical operations are addition (+), subtraction (−), multiplication (* or ×), division (/), brackets (grouping symbols used to indicate order of operations like (), [] and ) and exponentiation (^n or n, also called orders or indices).

Detailed explanation-5: -PEMDAS rule states that the order of operation starts with the parentheses first or the calculation which is enclosed in brackets. Then the operation is performed on exponents(degree or square roots) and later we do operations on multiplication & division and at last addition and subtraction.
