Where is the math field in D8

I needed to sum multiple values from the same row, like described in Drupal 10: How to do calculations with aggregated results of a row. I tried Views Aggregator Plus → , but couldn't get it to work. I found this issue and tried with Twig, which did work ... but you can't sort a custom field: #2223195: Views "Global: Custom text" field handler should not be sortable → .

I finally succeeded summing multiple values from the same row with Views Simple Math Field → , which also supports sorting. Thanks @andileco!
