An algebraic expression can have a mixture of numbers and variables, but it does not contain an equals sign.
A variable expression has at least one variable in it (which is usually a letter that stands for an unknown number).
No. If it consisted only of numbers it would be constant. There must be at least one variable in the expression.
You replace each variable by its value. Then you do the indicated calculations.
You can only get a specific number for an expression if you assign numbers to the variables. As an expression, the existing expression cannot be simplified.
Only if it has an equality sign otherwise it is an expression.
It is a numerical expression.
An expression.
A variable expression includes variables.
No, because numbers never vary. A variable expression must have something in it that can take on different values, usually a letter, like 'x' for example.
A polynomial is a linear combination of non-negative integer powers of a variable. A linear combination means you can multiply the terms by constant numbers before summing them. The terms can consists of only positive integer powers of the variable or a constant.
A mathematical expression in its' most simplistic form, merely assigns a value to a variable. Don't confuse an expression with an equation. An equation requires a solution. An expression cannot be "solved". It only allows you to determine the value of a variable. This is the expression in words "x is equal to 3" (X is the variable which is equal to the constant number 3) This is the expression in numbers "x=3" The expression in words "y is equal to 6" (Y is the variable which is equal to the constant number 6) The expression in numbers is "y=6" I hope you understand now.
No, you can only simplify an expression. To solve for a variable, it must be in an equation.
No, a unary expression consists of one operand and one operator
You replace each variable by its value. Then you do the indicated calculations.
A expression that only contains numbers is a Numerical
A numerical expression!
No, not all expressions contain variables. An expression is a mathematical phrase that combines numbers, variables, and mathematical operations. A variable is a symbol that represents a quantity that can vary, such as x or y. Some expressions may only contain numbers and mathematical operations, such as addition, subtraction, multiplication, and division. For example, "3 + 5" is an expression that only contains numbers and the addition operation. However, an expression that contains at least one variable is known as an algebraic expression, and this type of expression is commonly used in algebra to represent mathematical relationships between variables. For example, "2x + 4" is an algebraic expression that contains the variable x and represents a linear equation in which y is equal to two times x plus four.
There is, unfortunately, n equation in the question: only an expression. An expression cannot be solved for a variable.
