Detailed Description
Rearrange a sum whose left operand is a sum including a constant such that constants are grouped on the left:
![\[ (\alpha + s_1 u) + s_2 \beta \rightarrow (\alpha + s_2 \beta) + s_1 u \]](form_153.png)
![\[ (\alpha + s_1 u) + s_2 v \rightarrow \alpha + (s_1 u + s_2 v) \]](form_154.png)
