free math problem solver with steps

We should know how to use the facility of Free Math Problem Solver with Steps, which guides us how to follow the steps for solving the math problems online. These problems can be based on different topics. In general a child of grade 6 has the problems based on profit and loss, percentage, simple interest and the compound interest and how to solve the mathematical expressions having more than one operation.  To solve the problems of mathematical expression, we have certain set of rules to be followed, which tells us which mathematical operation is to be performed and then which operator needs to be followed.  This is called the hierarchy of operations to be performed. In the hierarchy of operations, we will follow the rules of BODMAS, which means the following:
 B stands for Bracket
O – stands for Of operation
D- stands for division of terms
M- stands for  Multiplication of terms
A – stands for the  Addition Operation
S- Stands for the Subtraction operation.
 Thus we observe that if we follow this hierarchy of operation, it is clear that every time anyone will perform the operation of solving the expression, we say that the   result for the given expression will remain same. Thus  when the result for the expression is to be calculated, we ensure that first we will open the brackets and for this the operations in the brackets are to be  performed, followed by  “ of “ operation, then we perform division, then multiplication , then addition followed by subtraction operation.
 In order to learn how to use online Calculating Confidence Intervals, we must be aware of the free online features available on the above topics.  To know about the curriculum and the subject available in Ap State Board Of Secondary Education, a child should be able to understand the subject online.
In the next session we will discuss about De Morgans law and if anyone want to know about Lines of Symmetry Shapes then they can refer Internet and text books for understanding it more precisely.
