Why do people need this calculator?

Apart from the regular calculator, people who study math are in need of Cramer's rule calculator for 3 equations. Because, when people work out lengthy problems, they may not have time to solve the system of three linear equations by Cramer's rule. At that time, solving for the given variables would be an additional burden for them in solving lengthy math problems. To reduce the burden of those people, we have provided this Cramers rule calculator for 3 equations  here.

Using the calculator in solving word problems

When people do preparation of solving word problems on matrix, they may have to spend time to get idea on "How to solve". In this situation, they would not like to spend time to solve for the given variables using Cramer's rule. And also they would not be able to use the regular calculators to inverse of a matrix. By using this online calculator, students will find much time to get idea of solving the word problems. 

Advantages of using this inverse calculator

School students have the topic "Solve the system of equations using Cramer's rule" in their 11th and 12th grades. They are given a system of simultaneous equations and they have to solve for the variables which are in the equations using Cramer's rule.They will solve the problem as directed in the question. But they are not sure whether the answer they got is correct or incorrect. At that time, they can check the answer they have received is correct or incorrect using this calculator.  .

Apart from the advantages explained above, this calculator can also be used to learn how to solve the system of simultaneous equations using Cramer's rule.

When students solve the system of three equations using Cramer's rule, they have to find many values like delta, delta x , delta y and delta z. When student find the above four values, if they do mistake in finding even in one of those four values, they will not get the correct answer. And also, it is bit difficult to check where the mistake has been done. At that time, students can use this calculator and they can come to know where they have done mistake.

                           Δ =
                           Δx =
                           Δy =
                           Δz =

                           x =

                           y =
                           z =

Note: If you get x=0, y=0 and z=0, the system may be inconsistent or it may have infinitely many solutions. To know more about this, please go through the instructions given below.
