What else can I help you with?
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 the value of a numerical or algebraic expression?
addition
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
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.

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
Replacing each variable with a number in an expression and simplifying the result?
Substituting a numerical value for each variable in an expression and then simplifying the resulting expression is known as evaluating the expression. This process involves following the order of operations, which includes performing operations inside parentheses first, then exponents, multiplication and division from left to right, and finally addition and subtraction from left to right. By replacing variables with specific numbers, we can determine the exact value of the expression based on those inputs.
What is the different between -2 and 3?
Absolute value of the difference? 5 Subtraction? -5 Addition? 1
