Math worksheet for subtracting integers, featuring 30 problems to calculate differences between positive and negative numbers.

Since the user has set all options (ExplainAnswer, TeachTopic, GeneratePractice) to false, I will proceed directly to solving the problems presented in the image and providing the final answers in a clear list format.

The worksheet asks to "Calculate each difference," which means we need to perform subtraction with integers.

Here are the step-by-step calculations for each column:

Column 1:
1. $10 - (-14) = 10 + 14 = 24$
2. $-12 - 7 = -19$
