+Performs free-form math functions/operations on time series data and numbers. For example, `$A + 1` or `$A * 100`.
 
-You can also use a Math expression to define the alert condition for numbers. For example:
+If queries being compared have **multiple series in their results**, series from different queries are matched(joined) if they have the same labels. For example:
+
+- `$A` returns series `{host=web01} 30` and `{host=web02} 20`
+- `$B` returns series `{host=web01} 10` and `{host=web02} 0`
+- `$A + $B` returns `{host=web01} 40` and `{host=web02} 20`.
+
+In this case, only series with matching labels are joined, and the operation is calculated between them.
+
+For additional scenarios on how Math handles different data types, refer to the [Math documentation](ref:math-operation).
+
+You can also use a Math expression to define the **alert condition**. For example:
 
 - `$B > 70` should fire if the value of B (query or expression) is more than 70.
 - `$B < $C * 100` should fire if the value of B is less than the value of C multiplied by 100.
 
-If queries being compared have multiple series in their results, series from different queries are matched if they have the same labels or one is a subset of the other.

 ### Resample
 
 Realigns a time range to a new set of timestamps, this is useful when comparing time series data from different data sources where the timestamps would otherwise not align.
