-== Variable ==
-In mathematics, a variable is a
-value that may change within the scope of a given problem or set of
-operations. In contrast, a constant is a value that remains
-unchanged, though often unknown or undetermined.[1] The concepts of
-constants and variables are fundamental to many areas of mathematics
-and its ''<u>applications.</u>''
-A &quot;constant&quot; in this context should not be confused with a
-mathematical constant which is a specific number independent of the
-scope of the given problem.

-variable is a number which does not have a fixed value. For ex ,the
-number 5 or the 100 or any other given number is not a variable. They
-are fixed values.(constant). Similiarly the number of angles of a
-triangle has a fixed value i e 3. It is not a variable.The number of
-corners of a qudrilateral is fixed (4 ) it is also not a variable.
-But the measurement of each side of a qudrilateral is not fixed.
+== Multimedia resources ==
-== Dependent and independent variables ==
-Variables
-are further distinguished as being either a dependent variable or an
-independent variable. Independent variables are regarded as inputs to
-a system and may take on different values freely. Dependent variables
-are those values that change as a consequence to changes in other
-values in the system.

-== Expressions ==
-An expression is a mathematical term or a sum or
-difference of mathematical terms that may use numbers, variables, or
-both.

-The following are examples of expressions:

-*2
-*x
-*3 + 7
-*2 × y + 5
-*2 + 6 × (4 - 2)
-*z + 3 × (8 - z)
-'''Example:'''
-Gangaiah weighs 70 kilograms, and Somanna weighs k kilograms. Write an expression for their combined weight. The combined weight in kilograms of these two people is the sum of their weights, which is 70 + k.
-'''Example:'''
-A car travels down the highway at 55 kilometers per hour. Write an expression for the distance the car will have traveled after h hours. Distance equals rate times time, so the distance traveled is equal to 55 × h..
-Example:
- There are 2000 liters of water in a swimming pool. Water is filling the pool at the rate of 100 liters per minute. Write an expression for the amount of water, in liters, in the swimming pool after m minutes. The amount of water added to the pool after m minutes will be 100 liters per minute times m, or 100 × m. Since we started with 2000 liters of water in the pool, we add this to the
-amount of water added to the pool to get the expression 100 × m +
-.
-To evaluate an expression at some number means we
-replace a variable in an expression with the number, and simplify the
-expression.
-Example:
-Evaluate the expression 4 × z + 12 when z = 15.
-We replace each occurrence of z with the number
-, and simplify using the usual rules: parentheses first, then
-exponents, multiplication and division, then addition and
-subtraction.
-× z + 12 becomes
-× 15 + 12 =
-+ 12 =
-Example:
-Evaluate the expression (1 + z) × 2 + 12 ÷ 3 - z
-when z = 4.
-We replace each occurrence of z with the number 4,
-and simplify using the usual rules: parentheses first, then
-exponents, multiplication and division, then addition and
-subtraction.
-(1 + z) × 2 + 12 ÷ 3 - z becomes
-(1 + 4) × 2 + 12 ÷ 3 - 4 =
-× 2 + 12 ÷ 3 - 4 =
-+ 4 - 4 =
