Multiplication has higher precedence than addition and subtraction in mathematics to establish a consistent order of operations. This hierarchy ensures that complex expressions are evaluated uniformly, preventing ambiguity in calculations. By prioritizing multiplication, we can simplify expressions and maintain clarity in mathematical communication. This convention helps in solving equations accurately and efficiently.
What else can I help you with?
Is it true Multiplication has a lower precedence than division?
No, that's not true. In standard mathematical operations, multiplication and division have the same level of precedence and are performed from left to right as they appear in an expression. This means that if multiplication and division are present in the same expression, you evaluate them in the order they occur.
What is operators 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.

What are the Mathematical Operators in Order of Precedence?
Mathematical operators have a specific order of precedence that dictates the sequence in which operations are performed in an expression. The general order from highest to lowest precedence is: parentheses ( ), exponents (or powers), multiplication and division (from left to right), and addition and subtraction (from left to right). When multiple operators of the same precedence appear, they are evaluated from left to right. This hierarchy ensures consistent results in mathematical calculations.
Does multiplication always be done before division?
No, multiplication does not always have to be done before division; they are performed from left to right based on their appearance in an expression. According to the order of operations (PEMDAS/BODMAS), multiplication and division are of equal precedence and are executed in the order they occur. Therefore, if division comes before multiplication in a mathematical expression, it should be performed first.
Which operators have same precedence as multiplication?
Multiplication, division and modulo all have equal precedence.
When simplifying an expression you perform which operations inside grouping symbols first?
Within parentheses or similar symbols, the same rules apply as when you don't have parentheses. For example, multiplication and division have a higher priority (or precedence) than addition and subtraction.Within parentheses or similar symbols, the same rules apply as when you don't have parentheses.

How can you overrule the precedence given by c?
You cannot overrule precedence in C, however you can use the rules of precedence themselves to dictate the order of evaluation. Parenthesis has the highest precedence therefore you can use them to change the order of evaluation. Consider the following function: void foo (int x, int y, int z) { int a, b; a = x + y * z; b = (x + y) * z; } Multiplication has a higher precedence than addition so given the values x=2, y=3 and z=4, the value of a will be 14. Parenthesis has a higher precedence than multiplication so given the same values, the value of b will be 20. Note that you haven't actually overruled precedence, you've simply used the rules of precedence themselves to dictate the order of evaluation.
What are the differences between precedence and associativity?
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 percedence of arithmetic operators?
The precedence (not percedence!) is BIDMAS (UK) or PEMDAS (US) The acronyms stand for: Brackets (Parentheses) Index (Exponent) Division and Multiplication which have equal precedence and are evaluated from left to right. Addition and Subtraction which have equal precedence and are evaluated from left to right.

What are the mathematical order of operators in Java programming?
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.
What is the math rule that you always remember?
The precedence rule PEMDAS which is a mnemonic for Parentheses Exponentiation Multiplication Division Addition Subtraction
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.
What is the order of precedence?
Exponentiation first, multiplication and division second, addition and subtraction last unless the order is altered by using parenthesis.
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
