Question: 1 / 400

When subtracting numbers with signs, what is the first step?

Change the problem into an addition problem

The first step in subtracting numbers with signs is to change the problem into an addition problem. This is based on the principle that subtracting a number is the same as adding its opposite. For example, if you need to subtract a positive number, you would add the negative of that number. This makes it easier to handle the signs and perform the calculation accurately.

Once the problem has been rewritten as an addition problem, you can more effectively determine the result by considering the signs of the numbers involved. This method also helps clarify the operation you are performing and can prevent mistakes when dealing with negative numbers, as you are directly working with addition.

The other options do not effectively address the initial step required when working with signed numbers in subtraction.
