-先处理加法，后处理减法，后五个加法是带进位加法   
-$t_0=t_0 + Y \ast O_0$  
-$t_1=t_1 + Y \ast O_1$  
-$t_2=t_2 + 0$  
-$t_3=t_3 + 0$  
-$t_4=t_4 + t_0$  
-$t_5=0 + 0$

-接着处理减法，假定a<sub>0</sub>是  $Y \ast 2^{32}$  的低64位，a<sub>1</sub>是  $Y \ast 2^{32}$  的高64位。后四个减法是带借位减法：  
-$t_2=t_2 - Y$  
-$t_3=t_3 - a_0$  
-$t_4=t_4 - a_1$  
-$t_5=t_5 - 0$  
+**依然采用先减后加！**
