double digits

How do I make it so that (using the calculator object) I can click for example, 1, then 2 , and it will store that as 12, and then click add and then 5, and the answer will display as 17.I can click 1-9 and make them add, divide, multiply and subtract, but double digits is proving to be a bit of a challenge.

uhmm im not sure if this is what you mean, but for example if you have bunny move up 1 meter, click on the 1 meter, then click on other,type for example 7meters, then click the 7 after you hit ok,then click math, then click +,-,*, or /, then click other and type the number you want it to be -,+,*,or / by! It doesnt show the answer in the line of code it will show for example ( 7 / 2.2 )and it will automatically do the math when you click play.

sorry for making what i just said so hard to understand but i have to go so i cant check over it sorry, Trevor

by the way tell me if it works for you, or if i didnt even answer what you were asking

Here's what you need to do if all you want to do is perform those four simple mathematic operations:

-create three number variables under the world, one called num1, one called num2, and one called finalNum. Set their initial values to 0

-create five boolean variables: addYN, subYN, mulYN, divYN, and numMove. Set all of them to false.

-write a method under the world called numberCheck which is called whenever any of the number buttons are clicked and which passes the number clicked as a parameter (if mouse is clicked on numButton3, world.numberCheck [number == 3]). The method should look like this:

if world.numMove
(do nothing, for now)
else
if world.num1 == 0
num1 set value to (the number the user clicked on)
else
num1 set value to (num1 * 10) + (the number the user clicked on)

-write an event which sets numMove to true when the add, subtract, multiply and divide are pressed, and sets the corresponding boolean variable to true as well (the add button makes addYN true, etc.)

-now, go back to the numCheck method, and put this in the first part of the first if/else if statement (the one that checks to see if numMove is true)

if world.numMove
if num2 == 0
num2 set value to (the number the user clicked on)
else
num2 set value to (num2 * 2) + (the number the user clicked on)

-Finally, write a method which is called when the equals button is pressed called calculate, which looks like this:

if addYN
finalNum set value to num1 + num2
else
if subYN
finalNum set value to num1 - num2
else
if mulYN
finalNum set value to num1 * num2
else
if divYN
finalNum set value to num1 / num2

Now I haven't tested this code, so there might be a few bugs, but I spent a lot of time thinking about it, so it should work. Let me know if there are any problems, alright?

I havent tried either yet, but will get back to you both as soon as I do, thanks for the input

yehhh maybe what x2495iiii said ! sorry im not an expert at alice but i like to try and help people out with what i know ! or at least what i think i know
