Among other things, Set Up User Attribute plugin can be used to do some basic arithmetic operations, such as addition, subtraction, multiplication and division.
First, you need to get the numbers from the user, which can easily be done with User Input plugin. The numbers sent by the user will then be saved in the form of attributes you create.
Next thing you need is another set of user attributes that will show the total of the arithmetic operation. This is where you create a Set Up User Attribute plugin card. The Value section is the one that should contain the operations themselves, while in User attribute section you need to create attributes that will display the total.
To get the total, use the numerical attributes the bot acquired in User Input and either add, subtract, multiply or divide them using the “+”, “-”, “*”, “/” symbol respectively.
Not putting any symbols between the numbers will simply result in the bot showing a string of those numbers.
Last but not least, you need a text card which will display the total of the arithmetic operations you used. Make sure you put the attributes your bot has acquired in the previous step into the card.
