Game - how to set up 'Calculator'

You can use the Calculator format in Scratcher to help your visitors get a price estimate, calculate savings, or perform other calculations. The only limit is your imagination.

The Calculator consists of three fundamental elements that are required for it to work:

1. Input: The first element is the input.
2. Calculation: Based on one or more inputs, you can create a calculation, which is the second element.
3. Result: When you have a calculation, you can use it to display a result.

You can use both pre-defined numbers or variables to create a calculation.

Example:

Imagine you are a retailer of slush ice machines, and you want to make it easy for your customers to calculate how much water they need to add if they use a certain amount of slush ice concentrate.

You know that all concentrates you sell are mixed 1:4 (concentrate:water). Therefore, you can create an equation that says: x = y * 4. Rephrased, this is "How many litres of water do I need when I have used 1.5L of slush ice concentrate?" → 1.5 * 4 = litres of water.

Your calculator is set up as follows:

• How many litres of concentrate have you used? (This will be our variable)
• We know that our mixing ratio is the same as multiplying the variable by 4.

You can also use calculations for intermediate steps. Staying with the slush ice machine analogy, if you want to help the customer know approximately how many cups of slush ice will come out of the mixture they just calculated, you can create another calculation for that.

You know that a cup is 0.25L. You now have a calculation that tells you the total amount of water and concentrate. Start by creating a calculation that says "answer" * "calculation" (how much concentrate + how much water you need) = the total mass.

Now you can calculate how many cups of slush ice that will produce. You know that 0.25L is the same as ¼ litre, meaning that one litre requires 4 cups. Create a new calculation that says "calculation" * 4.

How to set up a Calculator

1. Start by creating a Quiz, either by creating a brand-new campaign or by adding it as a new page in an existing campaign.
2. Click on the quiz itself, then click on EDIT quiz and change game format.
3. You will now have the option to choose a new range of quiz formats. Select "Calculator".
