Rule 1: Subtracting a positive number from a positive number – it's just normal subtraction. For example: this is what you have learned before. 6 – 3 are two positive numbers. So solve this equation the way you always have: 6 – 3 = 3.

Use the SUM function to add negative numbers in a range. Note: There is no SUBTRACT function in Excel. Use the SUM function and convert any numbers that you want to subtract to their negative values. For example, SUM(100,-32,15,-6) returns 77.

If you have a random pair of numbers and you want to know the delta – or difference – between them, just subtract the smaller one from the larger one. For example, the delta between 3 and 6 is (6 - 3) = 3. If one of the numbers is negative, add the two numbers together.

Tips. Google spreadsheets can also subtract using the MINUS function. "=MINUS(A1,A2)" is equivalent to "=A1-A2."

To perform a simple subtraction operation, you use the minus sign (-). To enter the formula in your worksheet, do the following: In a cell where you want the result to appear, type the equality sign (=). Type the first number followed by the minus sign followed by the second number.

When talking about operations, the opposite of “add” is “subtract”. When talking about the operators themselves, then the opposite of “plus” is “minus”. So when talking about the property of a number, then the opposite of “positive” has to be “negative”. So why does it matter?
