How to find the Unit Digit of a number
For the concept of identifying the unit digit, we have to first familiarize with the concept of cyclicity. Cyclicity of any number is about the last digit and how they appear in a certain defined manner. Let’s take an example to clear this thing: The cyclicity chart...Basics of Factors
Basics of Factors: What are factors? What does the term mean? If we go by the Latin translation of the word, it means ‘who/which acts’. Well, in our mathematical sense, factors are the ones that act for sure, but in this case they act on numbers....Tricks for Divisibility
Tricks for Divisibility Some basics tips and tricks that you can use for divisibility All whole numbers are divisible by 1. A number is divisible by 2 if it’s even. A non-zero number is divisible by 5 if it ends in 0 or 5. In order to check the divisibility of a...Divisibility Rules
Divisibility Rules A divisibility rule is a short cut for discovering whether a given number is divisible by a fixed divisor without performing the division, usually by examining its digits. Most of the divisibility rules are derived from a concept of remainders. The...Exponents
Exponents Exponents are a method used to express products of the same number. How would you write: 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2? Hard to repeat the above number in calculations, isn’t it? Well, exponents provide us the solution to the above problem. The above...
