# Absolute value in AREL (rails)

I need to do some absolute values ββin AREL. Basically you need to understand how to execute this line (in relational algebra) with ARel:

Suppose P is a table with columns value1 and value2:

```
Project((|p.value1 - 10| + |p.value2 - 10|) as match) P
```

Not sure if this is possible with AREL.

Thanks in advance!
