How To Use A Calculator?

Hola guys!! Today I am here to tell you how to use a Basic Calculator. How to use it is actually one of the best thing's I learnt in my professional course. All thanks to Mr. Vaibhav & Mrs. Neha Jalan who taught me how to perform multiple and tough calculations on the calculator.

As there are some keys like M+ ,GT, etc..you can see the image. These keys actually makes our calculations easy. Let me tell you how.

M+ is Memory Add. It adds the current value displayed on the screen to the stored value in the memory register. 

M- is Memory Subtract. It subtracts the current value from the stored value in the memory register. 

MR is Memory Recall. It recalls the current memory register value.  

GT is Grand total. It is same as MR key. Both performs the same function.

MU is Mark Up. It calculates an item's selling price or gross profit margin.

I'll give you one example. 

12+ (9*8) -(5*6) = ?

Firstly, press 12 on the screen and press M+. Then multiply 9 and 8 and press M+ again. Then multiply 5 and 6 and press M-. And then press MRC. You will get your result. For clearing memory pres MRC thrice.

Now, Let me tell you how to calculate 15th root of 1992 on calculator.

Firstly press 1992 on the screen. Then press 12 times square root key. Then press -1 then divide it by 15 then add 1 and then press multiply key and equal key simultaneously twelve times.

By this you can calculate any root of any number.

I  hope you guys got some help from this post :D
