We know very well the buttons of the calculator used for simple calculations, while the calculator has many more buttons. Far from using these buttons, most of us do not know what their work is?
We have been using calculator since childhood and are still doing it today. The calculator has a huge contribution in making our life easier. However, the feature of the calculator available in the mobile phone has reduced the use of the original calculator to a great extent. But there is no doubt that people who have to do a big calculation, their work cannot be done with a mobile calculator.
The calculator is usually used only for addition and subtraction.
We usually use calculators to do plus (+), min (-), multiply (x) and divide (÷). If there is too much, then we also use a calculator to extract percentages. We know very well the buttons of the calculator used for simple calculations, while the calculator has many more buttons. Far from using these buttons, most of us do not know what their work is?
Do you know the major functions of these particular buttons
If you usually use a calculator, then you must be looking at the m +, m-, mr and mc buttons. But have you ever used these buttons. 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. 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. Let us now tell you how much importance these buttons have and what work they do.
This button is called Memory Plus, whose main function is to add the calculus to the memory. Simply put, these buttons are used to multiply two different digits and derive the result of their product. For example, suppose we have to do a total of two calculations. We have 2 notes of 5 rupees and 5 notes of 10 rupees. Now we have to add all these together, then we will first multiply 5 by 2 and then press m +. Pressing m + will save its result, after which we will multiply 10 by 5 and then press m +. Now both our calculations have been saved. Now we will press the mr button to know the complete result. The mr button means memory recall, which is used to find the results.
This button is called memory minus, whose main function is to reduce the calculus to memory. Simply put, these buttons are used to multiply two separate digits by subtracting them. For example, suppose we have to do a total of two calculations. We have 5 notes of 10 rupees and 2 notes of 5 rupees. Now we have to subtract the product of these two. First we will multiply 10 by 5 and press m-. After this we will multiply 5 by 2 and press mr to get the result. We will get our answer.
Do not forget to press the mc button after all the calculations or else the results of your next calculation may be in error. mc means memory clear, ie whatever you have calculated earlier, it all becomes clear after pressing this button. You can easily understand the functions of all these buttons, so we are also showing you a video here.
