The mr button means memory recall, which is used to find the results. Now we will press the mr button to know the complete result. Now both our calculations have been saved. Pressing m + will save its result, after which we will multiply 10 by 5 and then press m +. Now we have to add all these together, then we will first multiply 5 by 2 and then press m +. We have 2 notes of 5 rupees and 5 notes of 10 rupees. For example, suppose we have to do a total of two calculations. Simply put, these buttons are used to multiply two different digits and derive the result of their product. This button is called Memory Plus, whose main function is to add the calculus to the memory. Let us now tell you how much importance these buttons have and what work they do. The biggest thing is that we do not know the working of these buttons, due to which we are not even able to use the calculator in full. Arc hyperbolic functions are defined by using natural logarithms in trigonometric functions. Let’s leave the use of this also, do you know the role of these buttons? Before discussing the role or work of these buttons, it is important to know that they must not have found a place in the calculator without any reason. If you usually use a calculator, then you must be looking at the m +, m-, mr and mc buttons. Far from using these buttons, most of us do not know what their work is?ĭo you know the major functions of these particular buttons We know very well the buttons of the calculator used for simple calculations, while the calculator has many more buttons. If there is too much, then we also use a calculator to extract percentages. We usually use calculators to do plus (+), min (-), multiply (x) and divide (÷). The calculator is usually used only for addition and subtraction. In this manual, cursor key operation is indicated as, ,, and.
