How to Program a Calculator pt 1: The Basics

[hubbabubbagloppop]

do you still need help? if you do please post more detailed copy of your program so i can debug it(aka find the error)

[Houdiniman111]

Good info.

[ggamefreak]

PLEASE RESPOND!... I made a program where you put in someones name and it tells you their bday... I put display and then the bday but now every time i put in someones name it tells me the same bday... And yes i put end at the end of the program

[TheComputerNater]

@ggamefreak Well, if you are talking about programming the birthday in while programming the program, you could do this: :Input "",Str0 :If Str0="(Friend's name)" :Then :Disp "(Friends Bday)" :Pause :End You can do more "If" "Then" Commands" Or you can do this: :Input "Bday1:",Str0 :Input "Name:",Str1 This will store the name and program as Str0 and Str1. You can reopen this with a new program like this: :Input "Name:",Str2 :If Str1=Str2 :Then :Disp Str0 :Pause :End

Who are these people who dislikes everything on every page?

I have just finished on my XO-game and a simple PONG-like game. In the PONG-like game a ball drops on a random location and you will have to collect it with a small paddle. The ball drops faster eacht time. You have 4 lives. The highscore of my classmates is 40 catches. :D its addicting to program.. :D i also made some small animations

[Thjaca12]

After learning all of the basic info from your videos I now make games like tetris and snake

[sorajsm]

@Thjaca12 Good luck!

[tym4n]

hi, do you know how to display a text and variable on the same screen?

[AlbatrossNecktie]

@tym4n Use the 'disp' command. If you are asking how to put it on the same line, use the output command.

output(4,6,A) would put whatever number is stored in A in the 4th row from the top and the 6th column from the left. Replace A with "A" to make it display the letter A instead of the number stored in A.

[a3a3q3]

u now how to put an y/n question in it to ? im really need that

[Lexy30000]

do you know where the "Ysub1" symbol is? i am trying to program a table so i want the answer to go to y1 and y2

[AlbatrossNecktie]

@Lexy30000 Try vars -> Y-vars

[Thjaca12]

Thx for teaching basics. Could you make a video about more advanced programs like games and animations?

[AlbatrossNecktie]

@Thjaca12 At this moment, I do not know how to make games or animations well enough to teach users via a tutorial. However, the link in the video description is extremely helpful on this topic. Thanks for commenting. :)

[dasa3]

Nice Rime of the Ancient Mariner Reference!

[AlbatrossNecktie]

@dasa3 Haha, nice catch! You are one of the few to realize where my bizarre screenname came from (you are certainly the first to say so).

[UScommando3]

Thanks for this guide! I had the same problem, nothing I could find really helped me to program, now I can at least do basic things.

[AlbatrossNecktie]

Great news! Glad these were helpful.

[modernmoders]

THANK YOU SOOO MUCH FOR THESE:D you literally saved my life in physical science. i am currently making programs for the whole class that makes solving the equations sooo much easier:) i LOVE YOUUUU!!!!!<3

[AlbatrossNecktie]

lol I appreciate the comment.

[jedibassman100]

on my calculator G is the universal gravitational constant (6.67x10^-11) as well as other physical constants. ^_^

thanks for clarifying some things!

[AlbatrossNecktie]

thanks for commenting

[theraz90]

Thanks

[AlbatrossNecktie]

No prob.

[wertui80]

thx it helps a lot

[AlbatrossNecktie]

very welcome

[budjibird]

thank you so much for the tutorials. now i know how to create my own programs! i'm always frustrated about my graphic calculator, but now i know how to use it so much better, thanks to you! :D

[AlbatrossNecktie]

Glad to hear it has helped. :)

[chemistrycoolguyscom]

where is the comma

[AlbatrossNecktie]

It's a button on the calc. It is above the numbers.

[nerohardy222]

haha ill need this for exams.

[nlim3]

Genius!!!!!  tyvm dude

[AlbatrossNecktie]

Should be fine. When the error comes up, instead of quitting the program, select the second option. It will access your program and show you immediately where the calculator fails to read it.

[Cheeseman543]

output is better because disp eventually slows the program. Also, i like input more because it doesn't have to show the variablasld;zv

[Cheeseman543]

i wrote a program that draws spirographs...

[mattcifelli]

Its a usb male to usb male not a firewire

don't go out buying firewire cables everybody

[AlbatrossNecktie]

Thanks.

[MrWaffleMast3r]

Could you please tell me how you could make the calculator say: hello randomly all over the screen (preferably an amount limit so it doesn't constantly put them on the screen)

[AlbatrossNecktie]

There are directions below for a similar operation.

[Tccvids]

thanks champ...made it easy for me to do what i wanted...

cheers

[AlbatrossNecktie]

Glad to help. :)

[PromBar]

can you make it display a word a multiple number of times

for example

Disp "Blah" * 23424

and it will print it 23424 times

that example doesnt compile on the calculator

how would one do this?

[AlbatrossNecktie]

You can make it display a number of times. Normally, I like to make it display an infinite amount of times if I do this, but you can install a counter.  What you do is make a "repeat" loop. This will make the programming repeat until a condition is met. Like so (parenthesis are for understanding, not programming):

:0 -> X (store 0 into X)

:repeat X=23424

:disp "blah"

:X+1->X (X plus 1 stored to X)

:end

[dnvegeta]

23424 takes too long. How about 50 times.

:For(N,1,50

:Disp "text

:End

[keithpetro]

Hmmm... Similar to VBScripting :D...

[Peonanoob]

To delete G or any other letter use the "delvar" function ti should look like this

:delvar G

you can also use this function to delete a graph if you were writing on the graphing screen

:text(1,1,"Hello World")

if you were to have a function in for Y1 in the Y= screen it would draw the line then write the text which is very time consuming so instead write

:delvar

:text(1,1,"Hello World"0

[Peonanoob]

sry left out some on my last command line but its

:delvar Y1

:text(1,1,"Hello World")

however you need the correct Y1 u just cant punch it in manually you mus go to vars go left to Y-vars the function and select which Y variant you need

[OlloX3]

Thanks this videos was VERY VERY usefull, but ive got one question. how do you "unstore" numbers. because you stored -9.8->G.

[AlbatrossNecktie]

You don't really need to. One way is to delete the memory. 2nd, +, mem mgmt/del, real will get you each variable to delete. Or you can simply store 0 in the variable after the program is finished. Otherwise, what is leaving G as -9.8 going to hurt, you know?

[bobsdfsdf]

hey i have a TI-Nspire, can you do a video about writing programs on it?

[AlbatrossNecktie]

My "expertise" is on the TI-83 and 84. However, the programming should still be the same. The buttons might be in different places, but the commands should be similar or even identical.

[idioticmonkey43]

question, i'm using my sister's graphing calculator which is a TI 83. i only have a wire that connects my calculator to my computer, is there another wire?

and also, when i connect my calculator to my computer, it asks me for a program/disk. do these calculators come with CD's? or is the program needed to install into the computer in the calculator?

[AlbatrossNecktie]

Answer, there is another wire. You know the end that plugs into your calculator? You can buy a wire that has that same thing on the other end, so you can connect calculators together. To transfer data, press 2nd X (AKA "link")

Also, I have a TI 84, so I am not sure about the CD. A CD came with mine, but it might not have come with yours. Chances are that you have a CD lost somewhere inside your house. I'd be surprised if it wasn't included, but someone please correct me if I'm wrong.

[jettz31]

Dude you ROCK!!! I've been watching your vid's all day. I have one question though, I went out and got one of these calc's to do standard deviations. Is there any way you can assist me in creating a formula to compute the standard deviation?

[AlbatrossNecktie]

Lol, thanks for the compliment. I can do you one better than making the program. It's already in the calculator! Most don't know this, though, because it's not easy to figure out. You have to know it exists.

You have a "stat" button on your calculator. If you press it and cycle over to calc, you will get everything. Press stat, edit, and you can input your data. Press stat, go right to calc, and select 1 var stats. It will spit out any number you can think of.

[AlbatrossNecktie]

There's also regression lines right there. To calculate a Z scores or percentiles, try normalcdf( and invNorm( under 2nd, vars. There are also more calculations with 2nd, stat, go right to ops. Lastly, you can reuse any of these numbers in your own calculations by pressing vars, statistics. Keep in mind that you have to calculate 1 var stats before you use these, because it assigns the most recently calculated numbers to those variables.

[LeChungProduction]

what are your other apps. can you make another vid.!!!!!

[AlbatrossNecktie]

I have only useful programs. Quadform does the quadratic formula, Triangle does the law of cosines, and some basic stuff like that. I will probably not make any more programming videos.

[dwight538]

WOOOOOOOOOOOOOOOT!!!!!!!!!!!!!

Thanks!

[AlbatrossNecktie]

You are very welcome. :)

[atre89]

i love you... GIANT HELP

[AlbatrossNecktie]

lol

thanks

[cloud4056]

Could you make a video on how to draw graphics for a game, and how to animate these into a game of your own to play as you please?

[AlbatrossNecktie]

Nope. I am finished making calculator tutorials. There are other tutorials out there on youtube that can show that sort of thing, but from what I have seen, they aren't very good. Probably the best thing you can do is visit the link in the video description. There aren't videos on those tutorials, but they do an excellent job of explaining how to make games and animations.

[AlbatrossNecktie]

:) Thanks for the compliment. It's nice to know my work is appreciated.

[jesusxfreak]

hey thanks a bunch for these videos, you definitely dont get the thanks you deserve but they helped me a lot
