Overview

Product summary

Review the store description, core capabilities, and common use cases.

Let's say you're typing an email, and need to do some quick math on the fly:

"Dear John,

Since we met on January 1, 1970, we've been together for [[2023 - 1970]] years. At midnight on new years' day, it had been approximately [[(2023-1970) * 365 * 24 * 60 * 60]] seconds..."

Once you have installed the extension, you can type your email exactly as you see it above, and the math between the brackets will be done for you as you type. ("...we've been together for 53 years...")
