In mathematics, the order of variables in an expression, such as "y before x," often follows conventions or specific contexts. For instance, in coordinate geometry, the convention is to write points as (x, y), indicating the horizontal and vertical axes, respectively. However, in certain mathematical contexts, such as functions or equations, the order can vary based on the specific relationships or dependencies being represented. Ultimately, the arrangement is determined by the conventions of the field or the preferences of the author.
The verbal phrase "the sum of x and y" can be translated into the algebraic expression ( x + y ). This expression represents the addition of the variables ( x ) and ( y ).
That depends on the value of x and y. As an expression, "x + y" can't be simplified.
To factor out the expression: x2y-y3 First factor out one "y": y(x2-y2) The expression x2-y2 is a difference of squares, which factors as well: (y)(x-y)(x+y) This is the simplest factoring of the original expression.
The expression "y - x plus 12" can be written mathematically as ( y - x + 12 ). This represents a linear expression where you subtract ( x ) from ( y ) and then add 12 to the result. The final value depends on the specific values of ( y ) and ( x ).

The verbal phrase "the sum of x and y" can be translated into the algebraic expression ( x + y ). This expression represents the addition of the variables ( x ) and ( y ).
As a term of an expression: x-y
It is x*x + y*y*y*y
on a coordinate grid, X always comes before Y
Y = X- 2 one number before x is odd, two numbers before is even
X divided by Y
That depends on the value of x and y. As an expression, "x + y" can't be simplified.

Simply put, an expression does not need an equal sign, while an equation does. Equation: x+y=z Expression: x+y
y,x
