Microsoft Excel spreadsheets can handle inventory: what you have, what you had, what you sold and what you have left. You can input figures into a Microsoft Excel spreadsheet and subtract a number from what you originally had in inventory to determine what's left. You can use negative numbers to show the difference; for example with "15 - 10," this equation is actually "15 + (-10)."
You can format the way negative numbers appear in your spreadsheet. Numbers can be formatted with a negative sign, with double parentheses, or by using the colour red.
