Total |
| Before |
1 u - 26 |
1 u + 13 |
209 |
| Change |
+ 26 |
- 13 |
|
| After |
1 u |
1 u |
222 |
Total number of buttons in the end
= 209 + 26 - 13
= 222
2 u = 222
1 u = 222 ÷ 2 = 111
Number of buttons that Harry had in the end
= 1 u
= 111
Number of buttons that Harry had at first
= 111 - 26
= 85
Answer(s): 85
