#### About Class 6 Maths Chapter 11

In 6 Maths Chapter 11 Algebra, we will study about the terms related to algebra and algebraic expressions. As we know that the branch of mathematics in which we studied numbers is arithmetic and the branch of mathematics in which we studied shapes is geometry. Similarly, in the algebra section, we will study the following thinks.
We will study how to use letters in maths. Use of letters will allow us to write rules and formulas in a general way. By using letters, we can talk about any number and not just a particular number.
Since letters stand for numbers, operations can be performed on them as on numbers. This leads to the study of algebraic expressions and their properties.
Letters may stand for unknown quantities. By learning methods of determining unknowns, we develop powerful tools for solving puzzles and many problems from daily life.
Note: Variables can take different values; they have no fixed value. But they are numbers. That is why as in the case of numbers, operations of addition, subtraction, multiplication and division can be done on them.

बक्स की ऊँचाई = h सेमी
बक्स की लंबाई
= ऊँचाई की 5 गुनी
= 5h सेमी
बक्स की चौड़ाई
= लंबाई से 10 सेमी कम
= 5h – 10 सेमी
