• 使用两次 11：$$11+13+11\times(14-12)=46$$
• 使用两次 12：$$(11+12)\times(12+14)/13=46$$

• $$14+12\times(13-11)=46_{oct}$$

• $$(11+12)\ll(14-13)=46$$
• $$(11+12)\times\left\lceil\frac{14}{13}\right\rceil=46$$
• $$\sum_{i=13}^{14}{(11+12)}=46$$
• $$(11+12)\times\left|\left\{13,14\right\}\right|=46$$（这里大括号代表集合）
• $$(11+12)\times\left(e^{14i\pi}-e^{13i\pi}\right)=46$$

• $$11_{bin}+12_{oct}+13_{dec}+14_{hex}=46_{dec}$$

So what do you think? Did I miss something? Is any part unclear? Leave your comments below.
