A technique to find approximate solutions to equations that cannot be solved easily using standard algebraic methods
Only when specifically told to do so in the question
Approximate solutions, not exact
Start with 2 values: one too big, one too small
Choose value between previous two, closer to target
Continue narrowing down the range between closest values
Take exact middle value between final two values
When two values differ by only 1 in the final digit
Always show your working clearly
Use a clear table with xxx values, results, and too big/small
Giving final answer to wrong number of decimal places
