Subtract a 1-Digit from a 2-Digit (No Regrouping)

🥞 Stack it for subtraction! You can subtract vertically just like you add vertically, column by column.

Lesson 2

Concept

Stacking makes subtraction fast and organized. 🎯 **The Subtraction Stack:** **Example: 56 - 4 = ?** 1. **Stack perfectly:** Write the 56. Write the 4 perfectly underneath the 6 in the Ones column! 5 6 - 4 -------- 2. **Subtract down the Ones column:** 6 - 4 = 2. Write the 2 at the bottom. 3. **Subtract down the Tens column:** 5 - 0 (the empty space is a zero) = 5. 4. **Answer:** **52**. It's just single-digit math, holding onto its bigger Tens partner.
