Subset Definition: A set X is said to be a subset of another set Y, If all elements of set X are elements of set Y. In other words, the set X is contained inside the set Y. Symbol ‘⊂’ is denoted for ‘Subset of’ or is ‘Contained in’. If set A is a subset of set B, then it […]
Read More →Set Theory : Equal and Equivalent Sets Definition & Examples: Equal Sets The two given sets have member of elements and the number of elements are exactly same, then the sets are called Equal Sets. The elements could be anything like picture, numbers, alphabets. The repetition of elements and the order of […]
Read More →Union of sets Definition: The Union of two sets A and B is the smallest set, which contains all the elements of both sets and taking every element of both sets A and B, without repeating any element, or common elements being taken only once. The symbol ‘∪’ used for the Union of two sets. Symbolically, we write union […]
Read More →Positive Numbers Definition- A Positive Number is a number, that is greater than zero. Example – 3 is a positive number(positive 3) and also written as “+” symbol in front of the number. Note- Zero is neither positive nor negative.
Read More →Square Root of a Number The inverse (opposite) operation of addition is subtraction and the inverse operation of multiplication is division. Similarly, The “square root” is the inverse operation of squaring that number. Square root of a number is number itself. Square of 1 = 1 x 1 = 1 = 12 […]
Read More →Set Theory In our everyday life we often speak about collections of objects. A particular kind of sets such as, a football team, a group of students, bunch of flowers, etc. In mathematics, we also come across the collections, For example – Whole numbers, factors, natural numbers etc. In simply we can say it’s a […]
Read More →Variables and Algebraic Expressions Definition: Variable Variables are symbol or letters that used to represent for unknown numbers or values. simply a single letter, that represents a number called the value of the variable. Example: The letters a, b, c, x, y, z, m, p, q are most commonly used for variables. In algebra the […]

The little threerepresents that it is cube root. The value of Index is 3, the Radicand is 8 and Radical symbol is […]
Read More →Arithmetic Mean Definition: The sum of the numerical values of each and every observation, that is divided by the total number of observations is equal to “Arithmetic Mean”. Arithmetic Mean is also called average or mean. The Arithmetic Mean or mean or average is defined as, Symbol: X = (𝚺xi)/n X = Mean […]
Read More →Pictograph There are many methods of representing statistical data pictorially. One of them is picture symbols or icons. Interpreting the picture graph means drawing some conclusions from it. In graph theory, a “Pictograph” is a graph that represent (numerical) statistical data through pictures symbols or icons. A pictograph […]
