This video talks about the topic consistent and inconsistent equations for the chapter Pair of Linear Equations in two Variables. While solving a pair of linear equations either we might get a ...

In this video we will learn about the plotting of graphs for a pair of linear equations in two variables. Two straight lines are obtained when we plot a pair of linear equations on the graph paper ...

Sometimes in mathematics we like to use letters to represent numbers. The ‘value’ of these letters can change according to certain rules or conditions we are given – hence we can call them variables.

Grade school math students are likely familiar with teachers admonishing them not to just guess the answer to a problem. But a new proof establishes that, in fact, the right kind of guessing is ...
