Read More →Simultaneous equations by Elimination Method Steps for solve linear equations with elimination method. Step 1: First we arrange both equations in standard form, placing like variables and constants one above the other. Step 2: Choose a variable (x or y) to eliminate, Multiply both equations by a suitable(non zero) constant to make the coefficients of one […]
Read More →Mode – Definition – Examples In this tutorial, we shall learn about mode and how to find mode of a given observation. Definition: The mode of a data set is the value, occurring most frequently in set of observations. In other words, a data set having highest frequency of observations is its mode. How to find […]
