1+3+1+2+0+1+3 =11, 1+1=2 

2. The symbolic meaning of number Two is kindness, balance, tact, equalization, and duality. The number Two reflects a quiet power of judgment, and the need for planning. Two beckons us to choose. The spiritual meaning of number Two also deals with exchanges made with others, partnerships (both in harmony and rivalry), and communication. Two urges us out of our indecision, calls us to unite with like-minds, and like-ideals.
