Let’s solve each addition problem one by one. We can count on our fingers or use the number line to help — but since we’re doing it step by step, let’s just add them carefully.
1.
2 + 7
Start at 2, then count up 7 more: 3, 4, 5, 6, 7, 8, 9 → That’s 9.
2.
4 + 3
Start at 4, count up 3: 5, 6, 7 → That’s 7.
3.
5 + 4
Start at 5, count up 4: 6, 7, 8, 9 → That’s 9.
4.
4 + 6
Start at 4, count up 6: 5, 6, 7, 8, 9, 10 → That’s 10.
5.
5 + 2
Start at 5, count up 2: 6, 7 → That’s 7.
6.
3 + 6
Start at 3, count up 6: 4, 5, 6, 7, 8, 9 → That’s 9.
7.
2 + 4
Start at 2, count up 4: 3, 4, 5, 6 → That’s 6.
8.
3 + 5
Start at 3, count up 5: 4, 5, 6, 7, 8 → That’s 8.
9.
7 + 3
Start at 7, count up 3: 8, 9, 10 → That’s 10.
All answers checked and double-checked!
Final Answer:
2 + 7 = 9
4 + 3 = 7
5 + 4 = 9
4 + 6 = 10
5 + 2 = 7
3 + 6 = 9
2 + 4 = 6
3 + 5 = 8
7 + 3 = 10
