A variable is simply an unknown value. It can be represented by anything else other than numbers (since they won't be variables). For example, a+1 is a variable in an addition expression, b-c is a subtraction expression with two variables. Expressions need not be made up of only 2 items as well. The next line is a single expression as well:
q-w-e-r-t-y-u-i+o+p-a+s+d+f+g-32h+124j+73k-l+z+2x+c+7v-b+4n-8m

How do you solve expression variable not simplified?
To solve an expression that is not simplified, first, combine like terms by identifying and grouping similar variables or constants. Then, apply arithmetic operations (addition, subtraction, multiplication, division) as appropriate to simplify the expression further. If necessary, factor the expression or use algebraic identities to reduce it to a simpler form. Always check your final answer to ensure it is in its simplest possible state.
How do you phrase algebraic expression?
To phrase an algebraic expression, identify the quantities involved and their relationships using variables to represent unknown values. Use mathematical operations like addition, subtraction, multiplication, and division to connect these quantities. For example, if you want to express the sum of a number ( x ) and 5, you would write it as ( x + 5 ). Always ensure to clearly define any variables used for clarity.
What do you call the order use to do arithmetic in a numerical expression?
It is known as BIDMAS (UK) or PEMDAS (US) BIDMAS = Brackets, Index, Division, Multiplication, Addition, Subtraction. or PEMDAS = Parentheses, Exponent, Multiplication, Division, Addition, Subtraction. There is no porder between DM/MD and between AS: Division and multiplication are to be carried out left to right. Addition and subtraction are to be carried out left to right.
Why can you use addition to check your answer to a subtraction problem?
You can use addition to check your answer to a subtraction problem because subtraction is the inverse operation of addition. If you subtract a number from another and then add that same number back to your result, you should arrive at the original number. This relationship confirms the accuracy of your subtraction result, ensuring that the calculations are correct. If the sum does not match the original number, then there was likely an error in the subtraction process.
When addition subtraction and multiplication are use in a problem in that order which get done first?
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.
Explain how you know to use a variable in an addition or subtraction expression?
that we can use it
What does the variable represent in an addition or subtraction expression?
it is the number you would use to solve the problem
Do you add before you subtract?
In mathematics, the order of operations dictates that you perform addition and subtraction in the order they appear from left to right in an expression. This means that you should perform addition before subtraction only if addition comes before subtraction in the expression. If addition and subtraction are next to each other, you would perform them from left to right.

How do you use greatest common factor with addition and subtraction of fractions?
You don't. You use the GCF to reduce the answer once the addition or subtraction is complete.
Why are multiplication division addition and subtraction used in evaluating expressions?
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.

What is the abacus use for?
addition subtraction multiplication and division
In addition use in sentence?
In addition to his response I vote yes. or I like addition better than subtraction.

Why would you use addition to solve a subtraction equation?
because you undo the operation in the equation= to undo subtraction you add
