How do I create sprites thats contains number to operate?

Hello, I want to create objects that can to be operated like,for example, sum, subtract, divide and multiply. The idea is the following one: A box that jumps must clash with coins (as mario bros). These coins have numbers as for example as 2. After must hit with another coin with an operator as +, then must hit with another coin with the second number as 3. Finally 2 coins must appear with 2 possible solutions, example 5 and 7. If it hits with the coin that contains 5, the game continues, if it hits with the coin that contains 7, the game ends. ¿How I can assign numbers to the sprites of coins that can operate and give a result?

Thats is an example (the image not shows complete, please open the image in other tab)

Thanks

Use "instance variables" on those sprites, then you can add, subtract, etc on those variables of any given sprite instance.

Thanks you, but ¿ is posible use a randoms numbers assigned to sprites?, for example once time the first coin gets 2 and in other moment gets 5, currently when the game restart. I not want create sprites of numbers, because when i operate for example 3 x 6, this result give 18, and i cannot to create a sprite for each number of range 1-100. For this raeson i want to asign random values in coins.

Is possible?

Something like this?

Yea, you can do anything you want with those variables (within the typing constraints).

random() is a good system expression to learn.
