Change is usually the value of an expression before some operation subtracted from the value after the operation. Occasionally, subtraction may be replaced by division.
Order of operation means that you go from the left of your equation to the right always doing multiplication and division first and then addition and subtraction
We'll answer this generally, since you haven't provided an expression. A common technique for remembering the order of operations is the abbreviation "PEMDAS", which is turned into the phrase "Please Excuse My Dear Aunt Sally". It stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction".
multiplication/division from left to right, then addition/subtraction from left to right
George Jessel was the first to use the expression "Always leave them laughing"
First you have to solve the subtraction and in the next step you will factor it out.

The primary difference is that subtraction is an operation that is performed as part of an expression. For example.... 2X - 4 Whereas a negative sign is not an operation but associated with an individual term in the expression..... 2X + (-4) In the first example you are subtracting two positive "things" from each other. In the second example you are adding a positive "thing" and a negative "thing" together. You will notice that if you were to substitute a number in for X in either of these expressions, or graph them as linear equations, you would obtain the same results for both.
