You could count by 2 or by adding 5+5 or 5x2 but I think there is more than what I added
1. 5 + 5 = 10
2. 2 · 5 = 10
3. 10 · 1 = 10
4. 100 ÷ 10 = 10
5. 7 + 3 = 10
6. 6 + 4 = 10
7. 8 + 2 = 10
8. 12 - 2 = 10
9. 177,329,132 - 177,329,122 = 10
10 999,999,999,999,999 - 999,999,999,999,989 = 10
2. 2 · 5 = 10
3. 10 · 1 = 10
4. 100 ÷ 10 = 10
5. 7 + 3 = 10
6. 6 + 4 = 10
7. 8 + 2 = 10
8. 12 - 2 = 10
9. 177,329,132 - 177,329,122 = 10
10 999,999,999,999,999 - 999,999,999,999,989 = 10
