We had a sneak peek into calculations when we were exploring choices. Let's take a more in-depth look at it in this section. We are familiar with mathematical calculations, like the following example that we saw when we studied data items:
X = 10
Y = 8
Z = X + Y
What is the value of Z? While we can manually whip out a calculator and compute that Z = 10 + 8 = 18, robots use the calculation stage to apply these formulas to get the answer:
We can do a lot more than calculate numbers. In the next example, we will use the Calculate stage to prepare an email message for the requester of the item to let him know that the item has been added to the cart.
