grade 2 addition and subtraction quiz

📚 Quick Study Guide

🔢 Addition: Combining two or more numbers to find their total. ➕ Formula: Part + Part = Whole (e.g., $3 + 2 = 5$) 💡 Subtraction: Finding the difference between two numbers. ➖ Formula: Whole - Part = Part (e.g., $5 - 2 = 3$) ✏️ Regrouping (Borrowing/Carrying): When adding, if the sum in a place value column is 10 or more, you 'carry' to the next column. When subtracting, if the top digit is smaller than the bottom digit, you 'borrow' from the next column. ❓ Key Words for Addition: Sum, total, in all, plus, combine. 🔑 Key Words for Subtraction: Difference, less, fewer, take away, remain.
