Which best describe how to evaluate a variable expression?
To evaluate a variable expression, first substitute the values of the variables with their corresponding numerical values. Next, perform the arithmetic operations in the correct order, following the rules of parentheses, exponents, multiplication and division, and addition and subtraction (PEMDAS/BODMAS). Finally, simplify the expression to obtain the final value.
The numerical value of an expression?
Is the value obtained when all the variables have been given their value and the expression has been calculated according to mathematical rules.
The rules for simplifying an algebraic or numerical expression?
There are a few rules for simplifying an algebraic expression. Specifically, one should combine like terms, and then they should try to isolate the variable by doing the opposite, either multiplication or division.
Does the order you perform operations in numerical expression matter?
Yes, the order in which you perform operations in a numerical expression does matter due to the rules of operator precedence. According to these rules, operations are performed in a specific order: parentheses first, followed by exponents, then multiplication and division from left to right, and finally addition and subtraction from left to right. Failing to follow this order can lead to different results for the same expression. Therefore, it is crucial to adhere to these rules to ensure accurate calculations.
Does it matter in which order we do each operation?
Yea because the collection of rules that define which procedures to perform first order to evaluate a given mathematical expression.

What do parentheses mean in numerical expression?
In a numerical expression, parentheses indicate that the operations within them should be performed first, according to the order of operations (PEMDAS/BODMAS rules). This prioritization helps clarify calculations and can significantly alter the result if not applied. For example, in the expression (2 \times (3 + 4)), you would first calculate (3 + 4) before multiplying by 2, yielding a different result than if the parentheses were not used.

What is a set of rules used to evaluate expression with more than one operation?
order of operations:);evaluate powers first, parenthesis second, multiplication and division third (if there is a combination of the two it doesn't matter the order you evaluate), and addition and subtraction last (like multiplication-division it doesn't matter the order you evaluate these two, a helpful tool for this step is to change all minus operations to plus negative).
