Hello. I created a custom field in which I added the amount of the deposit that I ask my client on the quotes. I do not find how to make a multiplication in the liquid model.

I wish that the calculation takes the total of the estimate, carries out the multiplication by the personalized field then divides by 100.

I want to display the following sentence:

Deposit [custom field] so [calculated amount] …

Example for a quote of 100 €: 30% deposit therefore 30 €

it’s very easy to add two fields

Or to divide …

divided_by

but impossible to find the right syntax to perform a multiplication …

Thank you in advance for your help …
