# Bracketing Methods In most practical problems, the solution of such an equation lies in a range that is determined by physical constraints or by an educated guess. For example, if you are trying to solve a relation for my body mass, knowing that I am a human adult, my mass will never be negative, physical constraint, almost impossible to be less than 20 kg and will not exceed 300 kg. Of course, a good approximation would be the average human mass, around 75 kg, but we are interested, in this section, in a range of values in which the solution may be. This range is called bracket.

## What you should expect to learn in this lesson:
