precedence
Operator precedence (or, "order of operations") comes up in mathematics and computer programming and dictates which operations should be carried out first in evaluating a mathematical expression. The standard precedence used in math, science, and technology is: exponents and roots multiplication and division addition and subtraction Parentheses are also used for clarification or when the above precedence needs to be over-ridden. For example, with an expression line 3 + 2 * 4, you would start with the multiplication of 2 * 4, because multiplication has precedence over addition.
It is simply a collection of numbers and mathematical operations - until you add some further constraints or qualifications.
BODMAS is an acronym for helping remember the order for dealing with mathematical operators in a mathematical statement (operators are done according to the letters of the word from left to right):B - Stands for Bracket.O - Stands for "OF" or "Orders" (i.e. Powers and Square Roots, etc.)D - Stands for Division.M - Stands for Multiplication.A - Stands for Addition.S - Stands for Subtraction--------------------------------------------------------------------------------------------Note that the acronym is not totally correct if obeyed strictly: 1 - 2 + 3 gives -4 using BODMAS (as it says do the addition before the subtraction), but the correct value is 2.The fact is that there are two pairs of operators that have equal precedence and should be done in left to right order: Divide and Multiply, Subtract and Add. (Alternatively, if Divide and Subtract have a slightly higher priority in their pair and are done first, then the answer will always be correct, ie the acronym should be BODMSA.)1-2=-1-1+3=2Nothing wrong with BODMAS

Order of precedence is the priority of various operators in an expression, not overridden by parentheses.
The order of precedence is as follows:Parenthesis (expressions within brackets)Exponents (powers)Division & multiplicationAddition & subtractionOperations with equal precedence are calculated in left-to-right order.
Precedence of operators in an expression overridden by the use of parentheses
Mathematical operators have the standard precedence: parenthesis (brackets), orders (powers), multiplication/division, addition/subtraction. x + y * z implies x + (y * z) because multiplication has higher precedence than addition. When two operators have the same precedence (such as addition and subtraction), they are evaluated left to right. Thus x - y + z implies (x - y) + z.

In all popular high-level programming languages, the order in which operators are interpreted ("operator precedence") is vital to ensuring that all compilers execute instructions in precisely the same manner, as the "order of operations" rule is vital in mathematics. In the case of C and C++, arithmetic operators are executed prior to logic operators. For a detailed description of operator precedence, see the related links below.
Arithmetic operators (+, -, *, /, % ) have greater precedence over relational operators (<, >, <=, >=, ==, !=) in C language.
Precedence rules specify priority of operators (which operators will be evaluated first, e.g. multiplication has higher precedence than addition, PEMDAS).The associativity rules tell how the operators of same precedence are grouped. Arithmetic operators are left-associative, but the assignment is right associative (e.g. a = b = c will be evaluated as b = c, a = b).
Multiplication, division and modulo all have equal precedence.
