In x - 3 does absolute value change the subtraction into addition?
no, the absolute value does not change the subtraction into addition. it does however, change the difference to positive ( if the difference is negative)
What does it mean when a math problem says evaluate each expression?
When a math problem instructs you to "evaluate each expression," it means you need to compute the value of the given mathematical expressions using the specified numbers or variables. This involves performing the necessary arithmetic operations, such as addition, subtraction, multiplication, or division, to arrive at a numerical result. Essentially, you're simplifying the expression to find its value based on the provided inputs.
What is an expression in algebra terms?
In algebra, an expression is a combination of numbers, variables, and mathematical operators (such as addition, subtraction, multiplication, and division) that represents a value. Unlike an equation, an expression does not include an equality sign and cannot be solved for a specific value. For example, (3x + 5) is an algebraic expression where (x) is a variable. Expressions can be simplified or evaluated by substituting values for the variables.
What is the value of a numerical or algebraic expression?

What is an expression in mathematics?
An expression in mathematics is a combination of numbers, variables, and operators (such as addition, subtraction, multiplication, and division) that represents a value. Unlike an equation, it does not include an equality sign. Expressions can be simplified or evaluated to yield a numerical result. For example, (3x + 5) is an expression where (x) is a variable.
Steps on how to do value of y fractions using addition and subtraction?
Y/3 - 1/9 = 2/9
In x - 3 does absolute value change the subtraction into addition?
no, the absolute value does not change the subtraction into addition. it does however, change the difference to positive ( if the difference is negative)
What operation is the inverse operation of addition?
The inverse operation of addition is subtraction. Subtraction undoes addition by taking away a number from the sum to return to the original value.
When finding the value of an expression should you always complete any addition before subtraction?
No, addition and subtraction are performed in any order. Consider 6 + 3 - 2. You can do it two ways:6 + 3 -1 = 9- 1 = 8, or 6 + 3 -1 = 6 + 2 = 8.

Which operation of arithmetic is the inverse of addition?
Subtraction is the inverse operation of addition. Adding a number and then subtracting the same number will bring you back to the original value.

What is the value of the expression 5 2 plus 30 and divide 6?
In the absence of parentheses, multiplication and division are carried out before addition and subtraction. In this case, add 5 to whatever is happening with the five and the two.
What expression could you use with only multiplication and subtraction so that its value is 25?
8*5 - 15
How do you find the value of an expression in lowest terms?
To find the value of an expression in lowest terms, first simplify the expression by performing any necessary operations, such as addition, subtraction, multiplication, or division. If the expression is a fraction, factor both the numerator and the denominator to identify and cancel any common factors. Finally, ensure that the resulting fraction is in simplest form by confirming that the numerator and denominator have no common factors other than 1.
How do you use variables in an addition or subtraction expression?
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
