Because if you perform the operations in a different order your answer will be wrong.
Its only important if you want the right answer. If the wrong answer will suffice, than any order will do.
Many expressions involve two or more operations. When simplifying such expressions, it is important to perform the operations in the following order:1. Perform any operation(s) within group symbols, which are:a. parentheses ( )b. brackets [ ]c. braces { }d. fraction bar /e. absolute-values bar | |f. radical sign2. Simplify all powers.3. Multiply and divide in order from left to right.4. Add and subtract in order from left to right.If you don't follow this order of operations, you will find a wrong answer.
The use of parentheses allows you to control, or change, the regular order of operations. For example, if you have the expression 4 + 2 * 3, under the normal order of operations, you would perform the multiplication before the addition. To perform the addition first, you just add parenthesis so the expression reads (4 + 2) * 3 instead.
The two have the same precedence. If there are a number of additions and subtractions, you do them in the order they occur, from left to right - after having done multiplications and divisions of course.

Yes, unless all of the operations are additions, or all of them are multiplication. Otherwise, changing the order will change the result. The order of operations is determined by parentheses, or if none are present, by the PEDMAS sequence.The order in which mathematical operations must be done has the acronym PEDMAS or PEMDAS. PEDMAS or PEMDAS, no matter how you spell it, gives the correct order for mathematical operations: 1. P - Parentheses, 2. E - Exponents, MD - Multiplication and Division, AS - Addition and Subtraction.
The two have the same precedence. If there are a number of additions and subtractions, you do them in the order they occur, from left to right - after having done multiplications and divisions of course.
The steps, in order, will depend on what you wish to do: convert from normal to scientific notation, the converse, perform one of the basic operations of arithmetic on numbers in scientific notation.
