Because if numerical expressions were simplified in any old order, then different orders would give different answers.For example,2+3*5 = 2 + 15 = 17But if you did it as 2+3*5 = 5*5 = 25The rules are there to ensure that the same everyone arrives at the same answer every time.
what is a special set of rules that gives the order in which calculations are done to solve a problem
A mathematical phrase that contains operations, numbers, or variables is called an algebraic expression. Algebraic expressions consist of constants (numbers), variables (letters representing unknown quantities), and mathematical operations such as addition, subtraction, multiplication, division, and exponentiation. These expressions can be simplified, evaluated, or manipulated using algebraic rules and properties.
That's called an "operator", for example, the plus sign in 3 + 4. The numbers are the "operands" - that is, the numbers (or expressions) operated upon. More precisely, a binary operator, since it works with two operands. In theory, an operand is just a special way of writing a function, since a third number is calculated, according to certain rules, from the other two.
Why not? 4 * 4 * 4 + 6 simpler as, 43 + 6 ============same with variables X * X * X + 6 X3 + 6 ===========and many other ways could be thought of here
The usual rules are: * Evaluate anything within parentheses first. * Evaluate multiplications and divisions from left to right. * Then evaluate additions and subtractions from left to right.
a set of rules used to evaluate expressions with more than one operation is the
This set of rules is called the Order of Operations.Many people remember this rule with the letters PEMDAS ("Please Excuse My Dear Aunt Sally")

they are the simple rules in algebra which make calculations a lot easier

A special set of rules, called the order of operations, can be used to solve expressions with more than one operation.Thank me by visiting,http://www.politicalsimpleton.comGood day!
