Best Answer

A pair of parentheses musts contain a operator and n elements must have n-1 operators, so a full parenthesization of an n-element expression has exactly n-1 pairs of parentheses.

The expression 'bareboat charter' means that the renter is only renting the vessel and not any crew or provisions. This means the renter is responsible for running the vessel.

Assuming there are no parentheses in the expression, then we can write it out exactly as you worded it: 4 * 4 + 4 * 4 + 4 - 4 * 4 To solve it then, you must first handle the multiplication: 16 + 16 + 4 - 16 Now you can add/subtract those numbers, and it gives you the final answer: 20
