How do you correctly multiply two variables in Liquid?

In Liquid, the syntax for performing mathematical operations on variables is specific. The correct way to multiply two variables, in this case, is using the filter syntax that provides a clear and readable way to perform the operation.

The choice that correctly employs this syntax is the one that uses the filter to multiply the two variables together. By utilizing the times filter, the expression {{ foo | times: bar }} effectively takes the value of foo and multiplies it by the value of bar. Filters in Liquid allow you to manipulate input and derive outputs using a defined method, and the times filter is a standard built-in method for multiplication.

The other options, while they may seem relevant, do not align with the proper syntax or available filters in Liquid for multiplication. Understanding this syntax is crucial for performing calculations correctly within Shopify themes.
