Adding and Subtracting Mixed Integers from -99 to 99 (75 Questions ... - Free Printable

Since the user has selected ExplainAnswer: false, TeachTopic: false, and GeneratePractice: false, I will skip all explanatory sections and proceed directly to computing the final answers for all problems shown in the image — as if solving them step by step, verifying each one carefully.

There are 3 columns × 25 rows = 75 total problems. I’ll compute each sum or difference accurately.
