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).

What is a sentence with precedence?
There's no precedence for your proposal; let's do it! Your early arrival gives you precedence for the day's tasks.
What is the difference between elementary algebra and Boolean algebra?
Here are the basic differences:elementary algebra:- Domain is the real numbers- Uses the operations of addition, subtraction, and multiplication- Uses the laws of associativity, commutativity, and distributivityBoolean algebra:- Domain is only two numbers- Uses the operations of conjunction, disjunction, and negation (AND, OR, NOT)- Uses the laws of associativity, commutativity, distributivity, absorption, and complements

What is the differences between Ontario and Alberta?
Ontario is two hours ahead of Alberta.
Associativity has no role to play unless the precedence of operator isHow much memory is required to store a value of type double?
yes
How do you evaluate an expression in hierarchy of operations?
Expressions are evaluated according to the language grammar. Operator precedence and associativity are derived from the grammar in order to aid our understanding, however the order of evaluation is independent of both because the C language standard does not specify operator precedence. The general arithmetic rules of precedence hold for most expressions such that parenthesised operations take precedence over orders followed by multiplication/division operations and finally addition/subtraction operations (as per the PODMAS acronym). Many of the more complex expressions we encounter can generally be evaluated according to the operator precedence table, which includes the associativity, such that operations with higher precedence are bound more tightly (as if with parenthesis) than those with lower precedence.
How many operators in c?
Quite a few. Some of them are: , () [] & * . -> + ++ += - -- -= * / % *= /= %= ! == <= >= < > != << >> >>= <<= & | ^ ~ &&
What is the C plus plus expression and operator precedence?
Precedence is determined by operators only. Every operator has a precedence in the range 1 through 17, where 1 has the highest precedence. All precedences have left-to-right associativity except 3 and 15 which are right-to-left. Precedence 1: scope-resolution operator Precedence 2: postfix increment/decrement, function-style type cast, function call, array subscripting and selection by reference or pointer. Precedence 3: prefix increment/decrement, unary plus/minus, logical and bitwise NOT, C-style cast, dereferencing, address-of, sizeof, new/new [] and delete/delete []. Precedence 4: pointer to member. Precedence 5: multiplication, division and modulo. Precedence 6: addition and substraction. Precedence 7: bitwise left/right shift. Precedence 8: relational operators (<, <=, > and >=). Precedence 9: equal/not equal operators (= and !=) Precedence 10: bitwise AND Precedence 11: bitwise XOR Precedence 12: bitwise OR Precedence 13: logical AND Precedence 14: llogical OR Precedence 15: ternary conditional, assignment and compound assignment. Precedence 16: throw Precedence 17: comma
What is precedence between relational operator and arithmetic operator?
Arithmetic operators (+, -, *, /, % ) have greater precedence over relational operators (<, >, <=, >=, ==, !=) in C language.
Which direction are java operators evaluated from?
It depends on the operator. Some have right-to-left associativity, some are left-to-right, some have no associativity.
Outline three essential differences in operation between common law and statute law?
Statutory law are laws passed by the legislature and have been written down and codified for use. Common law is based on precedence or case law.

What is the suffix of precedence?
The suffix of "precedence" is -ence.
What addition property do you use to change the order of an expression?
Commutativity and associativity.
What is temporal precedence?
Temporal precedence refers to an order of events. If something has temporal precedence, it precedes the event and is not the cause.
