How to use Rref on a Calculator

Advanced graphical calculators come with a modern rref function, which helps us solve such problems that are difficult to calculate by simple calculus methods.

Due to the calculus’s limited functionality, we face difficulty dealing with equations of augmented matrices. But the rref function now resolves our problem to identify the matrices, properties of a set of vectors, and much more.

But many people face difficulty using Rref Calculator, no need to worry we will provide you step by step guide.

If you have a graphical calculator that rref function, then following simple steps, you can find the solution to your difficult problems.

  • Start your work by entering the matrix menu; for this purpose, you will need to press [2nd][x^-1] to enter the menu, but some old versions also have a separate button for that function.
  • After that, press the right arrow and get access to the edit menu on your calculator.
  • In the next step, you will need to enter the matrix into the calculator; you should enter the size such as 2×2 or 2×3 or 3×3, whichever your matrix’s size. You just need to enter the number and then press enter after entry of each number.
  • Now a compulsory step that you need to the calculator’s proper function to come back to the main screen of the calculator. You can back to your main screen of your calculator by pressing “2nd” and then press “Mode” to quit.
  • In the next step, when you are at the main screen of the calculator, you will need to give command [2nd][X^-1], which will enter you in the matric menu again, but this time you will need to select the “math” menu from the list.
  • In the math menu, select matrix A; for that purpose, you will need to go back in the matrix menu by giving the [2nd][x^-1] command; you will see the “Names” menu here go into that menu.
  • In the names menu, press enter, which will make you able to select the matrix A.
  • In the next steps, you will need to close parentheses by [ ) ] command, after that press enter, it will make your matrix reduced.

  • It is also helpful if you make a proper note and keep it with you; by this written note, you will complete functions more quickly in the future or when you are new to use.

The above method is suitable for math problems and many other real-life problems regarding finance and pricing etc. This rref function makes things simple for us.
