■=r M Merge-factors-left. Merges arguments of -f, — , and
/, where the arguments have a common factor or a
common single-argument function EXP, ALOG, LN, or
LOG. For common factors, the 4- indicates that the
left-hand factors are common. Also merges sums where
only one argument is a product.

Merge-factors-right. Merges arguments of +, — , and
/, where the arguments have a common factor. The 4
indicates that the right-hand factors are common. Also
merges sums where only one argument is a product.
