NCERT Solutions for Class 6 Maths Chapter 11 Algebra: Algebra is one of the important parts of Mathematics. In algebra, we will study how we can use letters or symbols to represent numbers and quantities. The NCERT Solutions for Class 6 Maths gives basics of algebra. The chapter starts with the concept of variable. To understand the concept of variable let's consider an example. If we add 3 to a number the value is 10, what is the number? We know that the number is 7. In algebra the statement " If we add 3 to a number the value is 10" can be written as x+3=10 where x is known as a variable, here when x=7 then x+3=7+3=10. Now let's consider the statement "If we add 3 to a number the value is greater than 10", then the statement can be written as x+3>10. Here x can take values 8,9,10,........, that is x is not a fixed value, it is varying. So the variable is an alphabet or symbols which can take any numerical value. In NCERT Solutions for Class 6 Maths Chapter 11 Algebra, we will study how to form practical situations using variables, what is an equation and how to get the solutions of the equation by trial and error. In NCERT Solutions of higher classes (7, 8, 9 and 10) we will study how to form equations with one variable and two variables and how to solve them using different methods.
NCERT Solutions for Class 6 Maths we will study how to form an equation. To understand these let's consider an example mentioned in the NCERT Solutions for Class 6. " I am a special number. Take away from me a six! A whole cricket team, You will still be able to fix". The above statement can be represented as x-6=11. Here x is the special number, x can take any values. x-6 represents 6 is taken away from the special number and finally, x-6=11 represents I am a special number, Take away from me a six! A whole cricket team, You will still be able to fix. So, 11 is the number of players in a cricket team.

Q. 3. Pick out the solution from the values given in the bracket next to each equation. Show that the other values do not satisfy the equation.
Q. 3. A cube is a three-dimensional figure as shown in Fig 11.11. It has six faces and all of them are identical squares. The length of an edge of the cube is given by Find the formula for the total length of the edges of a cube.
Q. 1. Make up as many expressions with numbers (no variables) as you can from three numbers and Every number should be used not more than once. Use only addition, subtraction and multiplication.(Hint: Three possible expressions are make the other expressions.)
