1. Two numbers whose sum is zero - This describes **Additive Inverse** because additive inverses are pairs of numbers that add up to zero. 2. A way of breaking numbers into meaningful parts to help compute - This is **Part-Whole Reasoning**, a strategy to understand numbers by breaking them into parts. 3. A value that describes the distance from zero - This is **Absolute Value**, which measures how far a number is from zero regardless of sign. 4. A number written as a fraction, decimal, or integer - This defines a **Rational Number**, any number that can be expressed as a fraction or decimal. 5. The answer to an addition problem - This is the **Sum**. 6. The answer to a subtraction problem - This is the **Difference**. 7. Visual representation of adding/subtracting on a number line - This is the **Number Line Model**. 8. Numbers with the same absolute value but different signs - These are **Opposites**. 9. Rules for grouping, ordering, or combining numbers - These are the **Properties of Operations**. 10. Positive and negative quantities that cancel each other out - These form a **Zero Pair**.
