When using front-end estimation, the focus is on the values of the digits on the left side (or front-end) of the number being rounded. This strategy is useful when dealing with large numbers and can help to quickly estimate a reasonable answer. Adjusting for ignored digits or numbers can be done by rounding up or down based on the value of the digit immediately to the right of the one being ignored. For example, if the digit being ignored is a 5 or higher, the digit to the left would be rounded up. If it is a 4 or lower, the digit would be rounded down. This allows for adjustments to be made without requiring a full recalculation of the problem.
