If they are present in the expression you need to use them to evaluate the expression, if they are not, you don't.
You would not use any of them - at least not explicitly - to evaluate sqrt[ln(pi)], for example.
Addition is the inverse of Subtraction. Division is the inverse of Multiplication. and then visa-versa. :-) Addition is the inverse of Subtraction. Division is the inverse of Multiplication. and then visa-versa. :-) the Answer is subtraction
It is used in evaluating almost all mathematical expressions. The only exceptions are ones which involve only addition and subtraction, or only multiplication and division, or are so trivial that the are expressed in BODMAS order.
In Algebraic and even simple mathematical operations, convention to determines the order of calculations. This order is commonly remembered by the acronym PEMDAS, which stands for (and indicates the order of) parenthesis, exponents, multiplication, division, addition and subtraction.
the inverse of addition is subtraction and the inverse of multiplication is division. Of course, multiplication is just repeated addition so division is just repeated subtraction!
? An expression which is obtained by performing a finite number of the following operations on symbols representing numbers: addition, subtraction, multiplication, division, raising to a power.
BOMDAS Brackets (parenthesis), Of, Multiplication, Division, Addition, Subtraction
The rule is to evaluate terms according the following order of priority: In UK it is BIDMAS, an acronym for Brackets, Index, Division, Multiplication, Addition and Subtraction. In US, it is PEMDAS = Parentheses, Exponent, Multiplication, Division, Addition and Subtraction order of the mathematical order of operations." Note, that multiplication and division have the same priority; also, addition and subtraction have the same priority.
Yes they are closed under multiplication, addition, and subtraction.

The correct sequence for evaluating an expression typically follows the order of operations, often remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). First, resolve any calculations inside parentheses, then handle exponents, followed by multiplication and division, and finally perform addition and subtraction. This systematic approach ensures that expressions are evaluated consistently and accurately.
To solve BIDMAS (Brackets, Indices, Division and Multiplication, Addition and Subtraction) sums, follow the order of operations. Start with calculations inside brackets, then handle any indices (powers). Next, perform division and multiplication from left to right, followed by addition and subtraction, also from left to right. This ensures accurate and consistent results when evaluating mathematical expressions.
From Wikipedia: "PEMDAS is an acronym standing for the parentheses, exponent, multiplication, division, addition, and subtraction order of the mathematical order of operations." Note, however, that multiplication and division have the SAME priority; also, addition and subtraction have the SAME priority.
+ addition - subtraction* multiplication
In mathematical operations, addition, subtraction, and multiplication are governed by the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)). When addition, subtraction, and multiplication are used in a problem, multiplication is performed first, followed by addition and subtraction, which are executed from left to right. Thus, in a sequence where these operations appear together, multiplication takes priority over addition and subtraction.

It is used in evaluating almost all mathematical expressions. The only exceptions are ones which involve only addition and subtraction, or only multiplication and division, or are so trivial that the are expressed in BODMAS order.
It is a collection of numerical values along which are combined using arithmetic operations such as powers, addition, subtraction, multiplication and division.
