Precise means strictly correct or very exact. If you need something to be precise, like the positioning of a safety net for a stunt jump over a canyon, there's no room for error.
The word precise might make you think of a scientist carefully measuring the mass of a chemical for an experiment or an accountant double checking her calculations. But there's value to being precise in less formal situations as well. When making a grilled cheese sandwich, for example, it’s important that the arrangement of ingredients be precise: place a tomato in each corner and ensure that the cheese covers every inch of bread so that each bite is full of gooey delight.
