We can see that we have the same numerical answer (3), but that its value is different: 3 in the first calculation, but minus 3 (−3) in the second. Usually with a subtraction, we write the number we are subtracting from first, and the numbers we are taking away in any order after that. However, when we are performing a subtraction, we need to take extra care with the order of the numbers. When we are performing an addition calculation, the order in which we add the numbers does not matter.Ĩ + 3 + 5 is the same as 3 + 8 + 5 and gives us the same answer, 16. This simply means 2 less than zero or 2 below zero.įor more information, see our page on Positive and Negative Numbers. Numbers that have a negative value are written with a preceding ‘−‘, so minus two is written as −2.
