Interpret complex expressions by treating meaningful sub-expressions as single units.

Interpret an outside coefficient as the number of repeated groups

Problem

For \(12(h~+~1)\), the monthly quantity \(h~+~1\) is repeated for \(12~\text{months}\). Interpret the outside coefficient, the groups it counts, and one group's contents.

The coefficient counts one month, and that month has h + 13 units.

The outside coefficient is 12 for 12 months. Each month has h regular units and 1 extra unit.

The outside coefficient is 12 for 12 extra units per month. Each group is h + 1 months.

The outside coefficient is 12 for h + 1 months. Each group is 12 units.
