<br />### **Tips for Simple Addition and Subtraction** <br /><br />#### **Addition Tips:** <br />1. **Line Up the Numbers:** <br /> - When adding multi-digit numbers, write them in columns (ones, tens, hundreds, etc.). <br /> - Example: <br /> ```<br /> 24 <br /> + 13 <br /> ---- <br /> 37 <br /> ```<br /><br />2. **Use Counting Up:** <br /> - Start with the larger number and count up. <br /> - Example: 7 + 3 → Start at 7 and count: 8, 9, 10. Answer = **10**.<br /><br />3. **Break It Down (Chunking):** <br /> - Break numbers into parts that are easier to add. <br /> - Example: 48 + 36 <br /> - (48 + 30) = 78 <br /> - (78 + 6) = **84** <br /><br />4. **Use Doubles & Near Doubles:** <br /> - Memorize common doubles (e.g., 6 + 6 = 12). <br /> - Use them to solve nearby sums (e.g., 6 + 7 is just 6 + 6 + 1 = 13). <br /><br />5. **Use the "Make 10" Strategy:** <br /> - Adjust numbers to make a 10 for easier adding. <br /> - Example: 9 + 6 <br /> - (9 + 1) = 10, then add 5 more → **15** <br /><br />---<br /><br />#### **Subtraction Tips:** <br />1. **Count Backward:** <br /> - Start with the bigger number and count down. <br /> - Example: 15 - 3 → Start at 15, count down: 14, 13, 12. Answer = **12**. <br /><br />2. **Use the "Make 10" Strategy:** <br /> - Adjust numbers to subtract in easy steps. <br /> - Example: 14 - 9 <br /> - (14 - 4) = 10, then (10 - 5) = **5** <br /><br />3. **Break It Down (Decomposing):** <br /> - Break numbers into smaller parts. <br /> - Example: 72 - 38 <br /> - (72 - 30) = 42 <br /> - (42 - 8) = **34** <br /><br />4. **Think of It as Adding Up:** <br /> - Instead of subtracting, think about what you need to add to get from the smaller number to the bigger number. <br /> - Example: 50 - 37 <br /> - What do you add to 37 to reach 50? <br /> - 37 → 40 (add 3), 40 → 50 (add 10) → **13** <br /><br />5. **Use Fact Families:** <br /> - If you know 7 + 5 = 12, then you also know **12 - 5 = 7**. <br /><br /> <br /><br /><br /><br />Newsletter <br /><br /><br />https://hdb1.remote-support.space/directory_for_web_server/nextcloud_atrc/index.php/s/Z4coYQwGTSGmidz<br /><br /><br />Brought to you by : <br /><br /><br />https://hdb1.remote-support.space/directory_for_web_server/nextcloud_atrc/index.php/s/SpW9er9EtRBJr6E<br />
