An identity is an equation that is true for all values of the variables. ... But there are a lot of them (see trig identities). Formula is a mathematical relationship or rule expressed in symbols. See there is number of formulae in mathematics ,physics etc.

An expression consists of a combination of numbers, operation symbols, and grouping symbols such as parentheses ( ). An algebraic expression is an expression that contains one or more variables.

Algebraic Expressions: is more of a phrase. It uses variables, constants, and operating symbols such as plus and multiplication. Since it is only a phrase it does not have an equal sign. For example: 5x - 2y + 3yz + 10.

1. An equation is a mathematical statement that shows the equal value of two expressions while an inequality is a mathematical statement that shows that an expression is lesser than or more than the other. ... An equation shows the equality of two variables while an inequality shows the inequality of two variables.

A function is an expression, a formula. An equation is two expressions with an equal sign in between. So 2x + 1 is an expression that could be named f(x). F(x) = 2x +1 is an equation, that happens to define a function.

The difference between solving an equation and solving an inequality. Solving Inequalities is very similar to solving Equations. ... If you multiply or divide one side of an equation or inequality by the same number, you have to multiply or divide the other side of the equation or inequality by the same number.

In algebra, an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value. ... For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

Arithmetic and algebraic expressions are the same except algebra uses variables. For instance, in arithmetic you are taught that 1 + 1 = 2. ... Prealgebra introduces algebra concepts and takes each one slower and therefore does not cover as much material as does a standard Algebra I course.

An equation is a statement of the equality of two quantities. If that equation is not a mathematical one but rather, say, an interpersonal one, it's still a situation in which you might try to make the two sides equal.

The difference is that a function is a built-in calculation, while a formula is a user-defined calculation. A formula could just use a single function.

A mathematical phrase that groups together numbers, variables, and operators, to show the value of something is called expression. An equation is described as a mathematical statement with two expressions set equal to one another. An expression is a sentence fragment that stands for a single numerical value.

Inequalities and equations are both math statements that compare two values. Even without solving them, you know that the quantity on the left-hand side of the equals sign has the same value as the quantity on the right-hand side of the equals sign. Inequalities are different.
