Variables and Expressions Examples

In the previous post we have discussed about Subtraction of Fractions Calculator and In today's session we are going to discuss about Variables and Expressions Examples. When we study about the Algebra, the basic units of algebra are the constants and the variables. The equations are basically formed by the combination of  Variables And Expressions. Different terms, which we observe are combined with the help of the mathematical operators + and -.
To study about Variables And Expressions Examples, let us look at the following statement:
If two times of any number is added to 4, the result is 16.
In order to solve the given statement, we start as follows. Let us consider the variable x as the unknown number. Now when we talk about the two times of the unknown number, it simply means that the variable x  is multiplied by the number 2.
Further  we have that a number 4 is added to it, so the two terms will be 2x and 4, which we will be adding by the operator +. Thus the equation so formed by the statement will be as follows :
2x + 4 = 16
 Here we have the expression 2x + 4, where the terms of the equation are 2x and 4.
The value of x will be calculated by  solving the given equation. Thus we will get :
2x + 4 = 16
We will take 4 to another side of the equation and it will change from + 4 to – 4. So we get the equation as :
2x = 16 – 4
Or 2x= 12
 Now we observe that the left side of the equation is 2 * x, so we will take 2 to another side of the equation  by replacing the  multiplication with the relation of division. Thus we get :
X = 12 / 2
Or we write  x = 6 is the solution for the given equation.

 There  are different Properties Of Real Numbers like closure property, associative property, Commutative Property, Identity Property etc.  Icse Sample Papers 2013 are also available online.

Subtraction of Fractions Calculator

In the previous post we have discussed about Square Root Property and In today's session we are going to discuss about Subtraction of Fractions Calculator. Generally when we talking about the calculator then first thing came in our mind is that it is a kind of device that usually performs arithmetical calculation on numbers. Normally a simple calculator can perform multiply, divide, add and subtract percent related calculation and so on. If we talking about more advance calculator then they can also perform exponent, root and log related calculation to solve real world problem. Here we are going held a discussion on the topic of Subtracting Fractions Calculator.

It is also a kind of calculator that can perform the subtraction between two fractional values. To understand the concept of fractional calculator we need to understand the concept of fractional numbers and arithmetical operation that is subtraction. Fractional values are kind of number that shows two integer value in the ration form that is in the form of numerator and denominator. Suppose m and n are two integers then they can be represented as m / n. Here we need to perform subtraction between these fractional values. Subtraction can be define as a basic arithmetical operation that perform the reduction In value from another value. Now we can describe the process of Subtracting Fractions Calculator.

I ) For performing subtraction between fractional value first we need to calculate HCF of denominator values of both fractional values.

II ) After that divide the Calculated HCF value by each denominator value individually.

III) After performing above given step multiply the each result with their numerator value.

IV ) In last perform the subtraction between the obtained value and if required then simplify them.

The above given steps can easily describes the functionality of Subtracting Fractions Calculator.

In chemistry the concept of Ribonucleic Acid can be describe as a biologically molecule which is made up of long chain of nucleotide units. The Indian certificate of secondary education board provides previous years sample papers which is known as icse 2013 question papers.

Square Root Property

In mathematics, we will solve the square using different method. Here we will see Square Root Property and also see how to solve square root. Square root can be defined as a number in mathematics that is the multiplication of that same no twice, as (s) could be the square root of (t) like :

[s2 = t]

[√t = s]

Square root is represented by the symbol √r and √ is said to be radical sign.

In order to solve square root we need to follow some of the steps which are mention below:

Step 1:- To solve square root first we have to divide the digit which has to be square root into pairs, from the decimal point.

Step 2:- Then we have to draw the line over the pair of the digits.

Step 3:- Then calculate largest number such that the square root is same to or less than the next term pair.

Step 4:- Then we have to set the number over left side and also above the next digit pair.

Step 5:- Now we have to square a number and then subtract that number from the next digit pair.

Step 6:- Then after spread the bracket present in left side and then multiply the last number by 2, than put that number on left of the difference we have just find and leave the empty decimal place next to it. (know more about Square Root, here)

Step 7:- Now put the next term down and right to the difference.

Step 8:- Now we have to calculate the largest number to fill the blank space such that the number is times the number already exists, and should be less then the current difference.

Step 9:- Now we have to subtract the number just found.

Step 10:- And then we have to repeat all steps untill we get the result.

Using these properties we can easily solve the square root.
