When evaluating an expression, do these in this order:
- work out what is inside any parentheses first
- next, do exponents
- multiplication and division are done in the order you see them, from left to right.
- addition and subtraction are done in the order you see them, from left to right.

What is it called when you find the numerical value of an expression?
quantity!* * * * *Evaluating it.
What does it mean to evaluate each expression when there is an exponent?
To evaluate an expression means to find its numerical value. A power consists of a base and an exponent. According to the order of operations, operations inside parentheses (or other grouping symbols) are performed first, followed by the evaluation of powers ... then (*/) and (+-).
A combination of operations on variables and numbers is called an?
This is called algebra. In algebra you can have many operations. You can add, subtract, multiply, divide, square, cube, square root, factor, or distribute. There are others but these are the main ones. You use these operations to find the numerical value of the variable.
An agreed set of rules to evaluate numerical expressions?
order of operations
Does the order in which you perform operations in a numerical expression matter?
Yes, unless all of the operations are additions, or all of them are multiplication. Otherwise, changing the order will change the result. The order of operations is determined by parentheses, or if none are present, by the PEDMAS sequence.The order in which mathematical operations must be done has the acronym PEDMAS or PEMDAS. PEDMAS or PEMDAS, no matter how you spell it, gives the correct order for mathematical operations: 1. P - Parentheses, 2. E - Exponents, MD - Multiplication and Division, AS - Addition and Subtraction.
What is an expression that consists of numbers operations and grouping symbols?
Numerical Expression
What is a numerical expession?
An expression consisting of numbers and operations.
What is the term for a combination of numbers and operations?
A numerical expression.
What is the difference between simplifying and evaluating algebraic expressions?
Simplifying an expression is getting rid of any brackets or parentheses, performing as many operations as you can - including combining like terms. To evaluate an expression you would substitute the numerical values of all the variables, carry out all the operations (addition, multiplication etc) in the expression to reach the answer - the numerical value of the expression.
A numerical expression is made up of numbers and operations?
Yes.
What is expressions that contain only numbers and operations?

What is a combination of numbers and operations?
A combination of numbers and operations is called a Numerical Expression.
Is it true or false when the order in which you perform operations matters in a numerical expression?
