Addition & Subtraction Inverses Answer Key

This worksheet helps students explore how addition and subtraction undo one another through step-by-step practice. Students begin by simplifying expressions and circling the resulting values to observe patterns created by inverse operations. Next, they complete missing-number challenges that require identifying the number needed to maintain equality when using inverse operations. Learners then apply these concepts to solve for unknowns using the inverse of the operation shown. A final set of real-world word problems requires translating scenarios into equations and solving them using inverse reasoning. This worksheet strengthens number sense, equation solving, and understanding of operational relationships.
