The evaluate a algebraic math expression you first must substitute a number for each variable. Then you must perform the operation in the correct order.

The number is called the coefficient of the variable

It is the coefficient of the variable

A variable is a letter that represents a number. An expression that contains at least one variable is called variable expression, also called algebraic expression. A variable expression has one or more terms. A term is a number, a variable, or a product of numbers and variables. For example,3(x^2)y + 2xy + x - 7 is a variable expression, where you have 4 terms.When working with variable expression, you often use the substitution principle:If a = b, then a may be replaced by b in any expression.The set of numbers that a variable may be represent is called replacement set, or domain, of the variable. To evaluate a variable expression, you replace each variable with one of its values and simplify the numerical expression that results.Example: Evaluate the expression 2x - 4y for x = 5 and y = -9.Solution:2x - 4y= 2(5) - 4(-9)= 10 + 36=46

3020 is a number, not an operation. A number cannot have an inverse operation.

The term for replacing a variable with another value or expression is "substitution."

It is a poorly worded question. Any number in an expression can be a numerical variable.

A variable expression has at least one variable in it (which is usually a letter that stands for an unknown number).

Variable is any letter used in an algebraic expression, and can vary (change form) to be any number, and one variable means the same number in any single algebraic expression. Usually algebra is simplifying the expression or equation until you know what the variable is equal to.
