In Microsoft Business Central, users have a convenient feature for numeric fields such as cost or quantity. Instead of performing calculations separately, they can input mathematical formulas directly into these fields. The system automatically computes the result and displays the final value. For instance, if a user types "32+71" into a numeric field, Business Central will instantly calculate the sum and show "103" as the field's value. This functionality streamlines data entry and reduces the likelihood of calculation errors, enhancing overall efficiency in financial and inventory management tasks.
