How to use numeric fields

Let’s learn addition first. Suppose you have different types of chocolates in your shop. Now you want to add the total amount of chocolates. 

Start by creating a New Blank Form from the dashboard and put fields as you like.

For calculations, include the numeric fields that you want to calculate.

Click on the numeric field you want the results to show, and proceed to ‘Advanced Options’. You will find the ‘Calculation Field Settings’, now enable calculation from there.

Choose the fields you want to add, in this case, quantities of two different chocolates are added. Use the conventional signs for mathematical operation. Save the form. 

The output will be something like this. The subtraction functions in the same way.

Now, the multiplications. This time we want to find the total calories the chocolates contain. Add another numeric field for the calculations. Enable calculations as we did before.

As we want to multiply the total number of chocolates by the calories each of them contains, we simply multiply these two fields. Save the form after putting expressions.

The result is shown in the image below.

Now finally moving on to divisions. Suppose this is someone’s calorie intake per month. What would be their calorie intake per day? Dividing the total intake by 30 works, right?

Let’s calculate. 

Drop another numeric field, enable calculations, and proceed as we did before. But this time we need to divide it by 30(days). 

And we’re done with our calculations.

Result:
