◾️$\bf{\underline\green{SET:}}$

⟹ A set in mathematics is a collection of well defined and distinct objects, considered as an object in its own right.

⟹ The most basic properties are that a set "has" elements, and that two sets are equal (one and the same) if and only if every element of one is an element of the other.

▪️$\sf\blue{Example:}$

⇝The set of all computers in the world

⇝The set of all apples on a tree

⇝The set of all irrational numbers between 0 and 1.

◾️$\bf{\underline\green{FORMULA:}}$

⟹ The definition of a formula is a group of mathematical symbols that express a relationship or that are used to solve a problem, or a way to make something.

⟹ A group of math symbols that expresses the relationship between the circumference of a circle and its diameter is an example of a formula.

▪️$\sf\blue{Example:}$

⇝x = 2y - 7

⇝x/2 + 7 = 0
