How to Use a Basic Calculator

[@pacificskycrew]

yeh i needed this video 20 years ago... Cheers for the video

[@qerenyahu371]

Thank you so much. I missed so much in School. I am grateful for your time....

[@FrankMLoSchiavo]

You're welcome!

[@pillainag5378]

Yes. I too needed this 3 decades ago. Thanks

[@FrankMLoSchiavo]

Lol. You're welcome!

[@purplezinnia1139]

OMG! Thanks. I could tell from first hearing your voice I would learn something.

[@FrankMLoSchiavo]

And I can tell by your comment that you're going to learn a lot in life :)

[@baritony8763]

I learned to do this in school 45 yrs. ago on paper.A short,simple, much overdue learning experience.Thanks.

[@FrankMLoSchiavo]

My pleasure!

[@mrbriceno3949]

Thank you can’t wait to get my computing on, taking my first college chemistry class and professor has your video link posted.

[@FrankMLoSchiavo]

That's great! Thx for letting me know. I hope you enjoy your chem class :)

[@MrBork1999]

Most informative video on yt lol

[@Kajalk.90]

I like this video

[@rebecaaviles4911]

Needed help with knowing what the different M's mean and the function C vs CE

[@FrankMLoSchiavo]

I addressed the C (clear) and CE (clear last entry) buttons in the video. Maybe I'll make another video someday that addresses the memory buttons. Thx for the suggestion!

this video was made on my birthday

Thank you. Clear and well-presented.

I need some real-world examples to help to understand. How could you use 1/x to help with recipes? Why might you use the +- key? Eg. could you use that when doing a personal budget? How would that work?

[@FrankMLoSchiavo]

If a recipe will make enough for 6 people, but you want to make enough for 2 only, you could cut the recipe in thirds. If the recipe calls for 12 ounces of water, you'd type in 3, hit 1/x, and then multiply by 12 ounces to get the 4 ounces you'd need. In that case, it would be the same as dividing 12 by 3. If working on a personal budget, you might be adding a list of money coming in and money going out. As you add the numbers, some would be positive (money coming in) and some you'd make negative (money going out). In that case, making numbers negative would be the same as subtracting those values.

[@Solitaire001]

The "1/x" will give the reciprical of a whole number. Multiplying the reciprical of a number is the same as dividing by the original number. As an example, multiplying 10 by 1/2 is the same as dividing 10 by 2 (5). The "M+" and "M-" keys add/subtract the amount on screen to the memory. It is useful for storing numbers you reuse and also to keep a running total. As an example, you enter "20" and press the "M+", then you enter "5" and press the "M-". Press the "MRC" button and "15" will appear (20 - 5 = 15).

You explained that very well I got it the first time, not easily done for a 63 year old guy and all this electronics so thank you

You're welcome! Thanks for taking time to leave a comment :)

My pleasure, my friend.

[@StoneDeceiver]

Hello Dr. LoSchiavo Thank you for the quick tutorial, it was very quick and helpful. However, I found the Clear Entry section (3:27 - 4:18) to be unclear/confusing because the video formatting had led me to believe that the functionality of the Clear Entry Key would be substantially different than the Backspace Key and not just that the Clear Entry key would be functionally the same as pressing Backspace Key multiple times. From 3:27 - 3:47 I was being led up to the expectation that pressing Clear Entry was going to clear the 8 - and retain some other form of advanced function, but was then shown an example where using Backspace Key would be the proper/efficient key to use. At this point of the video I was confused thinking why is he not using Backspace key or explaining that the functionality of Clear Entry is the same as Backspace Key ? I thought perhaps it would be wise to put the explanations of Clear Entry and Backspace keys in the same section due to their shared functionality. Thanks again!

[@FrankMLoSchiavo]

Thanks for your comments! Although the CE key and backspacing can lead to the same end result, the CE key needs to be pressed just once, but the backspace key might need to be pressed several times if there are several digits in a number. My goal was simply to explain each key on the keypad. Thanks again for posting a comment :)

Thank you!!!

[@remuspierre]

Amazing stuff

[@pavithravenkatesh8369]

Beautiful explanation

[@FrankMLoSchiavo]

Thank you!

[@Tazxtehz]

From where do we get the cube sign???

[@FrankMLoSchiavo]

On the left, switch the calculator to scientific mode. You can cube numbers from there.

[@Tazxtehz]

thanks for the information ,but i am still confused that how do u get cube root?

[@FrankMLoSchiavo]

@@Tazxtehz I misunderstood your question. To get the cube root, use scientific mode, but click on the "2nd" button. Then you'll see an option for cube root.

[@duszeksmsaczek6394]

If all you have is a four-function, you type in your number, press X and two times equals.

[@BobPerry-ww5sl]

my cell calculator does not have all the keys that this one does, mine is much simpler in the sense of negative no for instance.

[@FrankMLoSchiavo]

My iphone has a simple calculator if I hold it vertically, but a much more sophisticated calculator if I hold it horizontally. Give that a try if you'd like another option.

[@azza2902]

Just wow

[@og1561]

thanks legend helps a lot % this was my research but other symbols help me too 💯🙏 thanks anyway 1000×

Thanks, I'm just refreshing... While I'm out and about, I do a lot of guesstimation for sake of time 😆

what does the X button do?

[@FrankMLoSchiavo]

It's not for tic tac toe, lol! It's for multiplication.

I’m just watching this for school

Awesome. Please share it with your friends if you found it helpful :)

Good😊

Thank you!

[@johnjackson3483]

It's unnecessary to hit [C] after a calculation. it will clear automatically when you start a new calculation.

[@FrankMLoSchiavo]

True, but some students get confused when they see the result of a prior calculation.

[@luvatune]

i just want the calculator....don't need the tutorial....thanx

[@FrankMLoSchiavo]

The calculator I used in the video is the basic "calculator" app available on computers running Windows. Actual calculators are usually inexpensive at stores like Walmart, and they last forever.

Sir how to start 0

[@FrankMLoSchiavo]

If you hit the "C" button it will clear the calculator and start at zero.

[@deepakmore4107]

How write 09 07

[@FrankMLoSchiavo]

Many calculators will not allow a leading zero, such as 09. However, some will allow you to set minimum values/figures, such as a certain number of digits after the decimal point. You'd need to check the specific setup options for your calculator to see which options are available.
