Cách 1:
2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 4
= 4 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 4
= 6 + 2 + 2 + 2 + 2 + 2 + 2 + 4
= 8 + 2 + 2 + 2 + 2 + 2 + 4
= 10 + 2 + 2 + 2 + 2 + 4
= 12 + 2 + 2 + 2 + 4
= 14 + 2 + 2 + 4
= 16 + 2 + 4
= 18 + 4
= 22

Cách 2:
2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 4
= ( 2 x 9 ) + 4
= 18 + 4
= 22
