Rounding

Rounding is a mathematical technique used to simplify a number by reducing the number of digits while maintaining a value that is approximately equivalent to the original number. This process is commonly applied to make calculations easier or to present numbers in a more digestible form. The rules of rounding generally involve looking at the digit immediately to the right of the place value you want to round to: 1. **If that digit is less than 5**, you round down (leave the target place value as is).
