Problem 2581=? [SOLVE]


 Masalah ni boleh diselesaikan dengan matematik biasa
iaitu tambah dan bahagi...

Solution:
2222 = 0 maknanya 2 = 0
5555 = 0 maknanya 5 = 0
1111 = 0 maknanya 1 = 0

2581
0+0+?+0 = ?

8809 = 6
0000 =  4 maknanya 0 = 1
9999 = 4 maknanya 9 = 1

8809
a+a+1+1 = 6
2a = 6-1-1
a= 4/2
= 2
8 = 2 

2581
0+0+2+0 = 2
2581 = 2

Proof:
9881 = 5
1+2+2+0 = 5

8193 = 3
2+0+1+0 = 3
