### I made a (very basic) calculator!

I've just shared a new project which is a calculator, it can do division, multiplication, adding, subtracting and square root problems! there are loads of lists and cloud variables for if you want statistics, if there is anything you think I can improve, tell me! You can see the project here.

IMPORTANT!

Please read this, it will be helpful for both of us.

I haven't made a project with actual code for nearly a year, so I have completely forgotten almost everything about computers and programming, please help revive my once really massive knowledge on computing again by pointing out any errors I have made.

I love how it's basic yet it works so well! I'm also working on a math project but I'm thinking about not doing it anymore because it's not really my style. Any tips?

### I made a (very basic) calculator!

if you want to do my method, then you would do this, but if you don't understand then just put all the scripts in your backpack and move them to your project, please credit me because i was ill when i made this: I love how it's basic yet it works so well! I'm also working on a math project but I'm thinking about not doing it anymore because it's not really my style. Any tips?

First of all, you need three variables:

(first number)WARNING: do not use the blue variable from sensing, make your own one from the data section. so it would be orange instead of blue.

(second number)

(answer :: variables) //this is a variable you made, not blue from sensing.

so how this will work is you would have one sprite, that sprite will ask you a question. the sprites first question would be asking you if you want to do division, multiplication, adding, or subtracting.

ask [Do you want to do multiplication, division, adding or subtracting?] and waitnow the next step requires a lot of code, so i'm going to word it. if you still don't understand you can take the script to your backpack with a comment attached to it saying ‘for violet_raven’. And use it for your project, but i would like credit. Because i was VERY ill when i made this project. so you need to program it so that if your answer is ‘division’ it will broadcast ‘division’ if it's multiplication, it would broadcast ‘multiplication’ etc.

if <(answer)= [multiplication]> then //this time you DO want a blue answer block, only for the maths question selection.now you want to make it so on the receiving end it does something, it will ask you what you want the first number to be and what to multiply by, divide add or subtract. A little like this:

broadcast [multiplication v]

end

when I receive [multiplication v]and then this will be the script for the answers:

ask [What do you want the first number to be?] and wait

set [first number v] to (answer) // for this you DO want the blue variable.

ask [what do you want to multiply by?] and wait

set [second number v] to (answer) //still using the blue variable. next step will use the variable you made that's orange.

set [answer v] to ((first number) * (second number)) //the little star means multiply in programming. because there is no 'times' key.(continued) on a normal keyboard. This is useful for if you want to mutliply. but if you want to divide, this would be the script.

set [answer v] to ((first number) / (second number)) //the slash means divide in programming, because there is no 'divide' key.(continued) on a normal keyboard. For adding it would be this:

set [answer v] to ((first number) + (second number)) //there is a plus on a normal keyboard so we just use an adding block.then you could program the cat to say the answer.

set [answer v] to ((first number) - (second number)) //There is a minus key on the keyboard, just use the dash key.

say(join (join (join (join (first number) [add] ) (second number)) [equals] ) (answer :: variables)) //keep in mind your using the orange variable saying 'answer'. nowAnd NEVER give up! have fun!
