They can but don't have to.
Yes.
addition and subtraction, you dummy
PEMDAS is an acronym to help you remember the order of operations in mathematical equations.First, you do expressions within Parenthesis and/or Exponents.Then, you do expressions involving Multiplication and/or Division.Finally, you do the expressions involving Addition and/or Subtraction.
Multiplication and addition.
Yes they are closed under multiplication, addition, and subtraction.
The correct sequence for evaluating expressions 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, evaluate any expressions within parentheses, then calculate exponents, followed by multiplication and division, and finally perform addition and subtraction. This structured approach ensures that expressions are simplified correctly and consistently.
Addition and subtraction are mathematical processes. They can be used in equations, which are statements that the values of two mathematical expressions are equal, but they are not equations by themselves.
BOMDAS Brackets (parenthesis), Of, Multiplication, Division, Addition, Subtraction
Such expressions illustrate the distributive property of multiplication over addition in the field of real numbers.
There are several addition expressions that can equal the number 7, depending on how you combine different integers. For example, you can represent 7 as 7 itself (7), or as combinations of smaller integers like 3 + 4, 2 + 5, and 1 + 6. If you also consider the order of the addends, the total number of unique addition expressions increases. However, the exact count can vary based on whether you allow repeated numbers and the range of integers considered.
