Pascal's Triangle Pascal’s Triangle  is a kind of number pattern.  Pascal’s Triangle is the triangular arrangement of numbers that gives the coefficients in the expansion of any binomial expression.  The numbers are so arranged that they reflect as a triangle. Firstly, 1 is placed at the top, and then we start putting the numbers in a triangular pattern. The numbers which we get in each step are the addition of the above two numbers. It is similar to the concept of  triangular numbers .  In this article, we are going to learn Pascal’s triangle history, definition, properties, patterns, formulas and examples with complete explanation. Table of contents: History Definition Construction How to use Patterns Properties Formula Expansion FAQs Pascal’s Triangle History Blaise Pascal was born at Clermont-Ferrand, in the Auvergne region of France on June 19, 1623. In 1653 he wrote the Treatise on the Arithmetical Triangle which today is known as the  Pascal’s Triang...

If you like Sudoku, there’s a good chance you’ll love KenKen. If you hate Sudoku, there’s a good chance you’ll love KenKen. Invented by Japanese mathematics teacher Tetsuya Miyamoto in 2004, KenKen is an elegant and rich logic puzzle with a few easy-to-understand rules, which helps explain why New York Times Puzzle Editor Will Shortz called it “The most addictive puzzle since Sudoku.” KenKen’s rules are straightforward: Fill in each square cell in the puzzle with a number between 1 and the size of the grid. For example, in a 4×4 grid, use the numbers 1, 2, 3, & 4. Use each number exactly once in each row and each column. The numbers in each “Cage” (indicated by the heavy lines) must combine — in any order — to produce the cage’s target number using the indicated math operation. Numbers may be repeated within a cage as long as rule 2 isn’t violated. No guessing is required. Each puzzle can be solved completely using only logical deduction. Harder puzzles require more complex deducti...

  Bar Graph Bar graphs  are the pictorial representation of data (generally grouped), in the form of vertical or horizontal rectangular bars, where the length of bars are proportional to the measure of data. They are also known as bar charts. Bar graphs are one of the means of  data handling  in statistics. The collection, presentation, analysis, organization, and interpretation of observations of data are known as statistics. The statistical data can be represented by various methods such as tables, bar graphs, pie charts, histograms, frequency polygons, etc.  In this article, let us discuss what is a bar chart, different types of bar graphs, uses, and solved examples. able of Contents: Definition Types of Bar Graph Vertical Bar Graph Horizontal Bar Graph Grouped Bar Graph Stacked Bar Graph Properties Uses Advantages and Disadvantages Difference Between Bar Graph and Histogram Difference Between Bar Graph and Pie Chart Difference Between Bar Graph and Line Grap...
