[ultraB9x]

i reallly really really hope all these tutorials arent copyrighted :P

[Houdiniman111]

THANK YOU!! this is the type of tutorial I like. And since I am trying to learn more, this is perfect.

actually, (0.8)C + (0.2)F = 70 = C-

[rlopez1221]

is it possible to put prompt n and type in a name or word and for the answer get a name or word if so could you help me

[TheTester0]

sweet 

[CrackingCody]

I am making a mini-cartoon program for my math class. Just wondering if anyone had a video or site to help me with that or if they could help me via messaging cause im stuck. or if you know a program and have the full code to it that could work too!

[jaybeebee14]

Is it weird that I do this for fun sometimes?

[AlbatrossNecktie]

@jaybeebee14 Nah...how'd you think I got started? :)

[noxious53316283]

@jaybeebee14 i do too.. and at the holidays... but thats my addiction xD

[fcdog555]

so gunna make a better version:D

thanks for the inspiration

[moviesmadebyjosh]

I also taught myself, and made a finals program. however, I use input instead of prompt. If you do: Input "Current Grade=?",C It will display the message and, once you type in the answer it stores in in C all in one step. It also doesn't show the C=? which is nice.

[AlbatrossNecktie]

@moviesmadebyjosh Wonderful news. Yes, using 'input' will work just as well.

[figgi0]

Yeah nice BASIC program hahaha

[rupluttaja]

how to delete program?

[AlbatrossNecktie]

@rupluttaja

"2nd + (plus key)"

go to mem mgmt/del

go to prgm

use the 'delete' key on any programs you wish.

[wowbotfixer]

i have no idea what are you doing how do you space words firstable?

second my class final mark is 30% final tasks include final exam and final activity and term tasks is 70%

[donovanfonseca]

THANK YOU very much for this tutorial.

I was able to apply this lesson with the quadrdic formula.

[AlbatrossNecktie]

@donovanfonseca I'm glad it was so helpful :)

[dragonkeyblade2]

Theres no ClrHome function on mine

[AlbatrossNecktie]

There should be. Make sure you are cycling sideways. The tab at the top should change. There are 3 tabs: "ctl", "I/O", and "exec"

[jamesschader]

@dragonkeyblade2 unless your calculator < TI-83

you should have it: press

I/O

8

[jamesschader]

@dragonkeyblade2 you must have a calculator earlier than my TI-83

[bmanfoley]

I thought I was beyond some of this information, but it looks I was missing some stuff. thanks so much

[AlbatrossNecktie]

No prob. Thanks for commenting = )

[carlostwist]

Thank you very much you realy helped me, now it's much easy to make my progrms

[AlbatrossNecktie]

Glad to hear it! Thanks for the comment.

[HLIDE713]

how do you place a space in between letters?

[AlbatrossNecktie]

alpha + 0

[HLIDE713]

thx for the video and answering my question but i was wondering if i could actually calculate my class average knowing the grades i made. tests being 80% and everything else like HW/Quiz(s)

20%

[AlbatrossNecktie]

It sounds like what you need is statistical. You will probably need to do this by hand as opposed to a program. Use stat, edit, and enter in the data. You can then use L1, L2, etc. (2nd + 1, 2nd + 2, etc) just as you would use a letter variable. For example, if L1 is tests and L2 is misc., you could do L1*.8+L2*.2->L3. Then, you can press stat, go right to calc, and press 1-var stats. The expression you would want for info on the class grades is 1-var stats L3. Hope that helped!

[rocketboy344]

how do you take a program off your calculator?? i cant figure it out

[AlbatrossNecktie]

Go to 2nd + "+". It will give you a "memory" menu. Select option 2. Then select option 7.  You should see a list of your programs. Press the delete button for any program you wish.

[rocketboy344]

thanks

[XsmashX1]

This might be a silly question but, will I be able to use the same variable "F" (for example here) in another program to store an answer?

I'm guessing yes. It'll just change the current value of that variable "F", correct?

[AlbatrossNecktie]

You are correct. In fact, it might be useful to establish the number "F" in one program and then use it in another program. F holds its value.

[Joemama85916]

How do you make the = sing?

[AlbatrossNecktie]

2nd+math. to get an arrow, it is the "sto>" button.

[ce082792]

Nice program, but I use Input instead of Prompt. I dont know if this works with Prompt, but you can make it say something else besides "C=?" by using the code: Input "your text here", C I would use this code for my program: Lbl 1 Disp "CURRENT GRADE? Input "C: ", C Disp " Disp "DESIRED GRADE? Input "N: ", N (N-.8C)/(.2) Pause Goto 1 the extra Disp adds an extra line between grades and the Lbl 1, Pause, and Goto 1 makes the program "restart" when the user hits enter

[BriWestEagles123]

how do u get it to store to the f function

[AlbatrossNecktie]

I'm not totally sure what you mean. If you want a function to store into Y=, go to vars, right to Y-vars, and click function. This gives you the right variable to store the function into.

[LastAnthony]

Hey man great program but can u tell me how to use it

[AlbatrossNecktie]

Watch from 4:34 onward.

[LastAnthony]

thank you man =]

[lulinda22]

can you clarify why you need to bustract the disired grade with the .8 of the final noteÉ

[AlbatrossNecktie]

If the final is worth 20%, then the rest of the grade is worth 80%. You take .80 times the grade you have, and that is the amount of points you have without taking the final at all. Add .20 times the grade on the final, and you have your grade in the class. The program simply reverses this and figures out what you need on the final instead of calculating your end grade.

[nygiantfan101]

thanks i kno java, HTML, and BASIC but this was a little new to me on what the different syntax means wat, thank you so much for the tutorial

[AlbatrossNecktie]

You are very welcome. :) I'm glad it was useful.

[OlloX3]

Please, feel subscribed by OlloX3!!!!

[AlbatrossNecktie]

Lol. Thank you -- I feel very subscribed right now.

[amo511]

where the store symbol?

[AlbatrossNecktie]

Right above "on".

"STO>"

[amo511]

Haha, I found that like 5 minutes after.

Thanks.;)

[bankaisharingan11]

what would u do if u were trying to solve for X n the equation Y=KX and u had Y and K

[AlbatrossNecktie]

Divide both sides by K.

Y/K=X

[stvn0988]

How do I put 2 conditions on an if statement?

[AlbatrossNecktie]

For example, if you want the condition to have X=1 and have Y>4, you would write it this way.

:If X=1 or Y>4

:Then

:BLAHBLAH

:End

Oh, and please only post your question on 1 of the videos. Posting it on all 4 is repetitive, redundant, and just saying the same thing over and over again. I will see the message if you post it.

[AlbatrossNecktie]

If you want both of the criteria to be met before BLAHBLAH instead of either one being met, then substitute "and" for "or".

[zachattackzach]

i know this sounds stupid but i can't find the space button on a ti-84 plus silver edition, can anyone help?

[AlbatrossNecktie]

Hit alpha, then zero. Above the 0 button, there should be a figure that looks like "_", but with little edge marks. That means (space).

[AlbatrossNecktie]

It's not easy to explain. It's also very difficult to put into 10 minute videos for youtube because of the amount of functions I would have to cover. However, you can check out the site in the video description which does a good job of explaining just about everything concerning programming.

hey man, can you please help me? How can I create games from my calculator?
