←=4↓=2■=5↗=9↙■0+↘↓→=???

←=4↓=2■=5↗=9↙■0+↘↓→=???

Answer 1

最好别用手机看

←=4↓=2■=5↗=9↙■0+↘↓→=???

分三种情况

①依题意得←=（4↓）=（2■）=（5↗）=（9↙■0+↘↓→）

∵4↓=2■=5↗

∴1↓=0.5■=1.25↗        且1■=2.5↗

而←=5↗

∴←=5↗=2.5↗+1.5↗+1↗

              =1■+1.2↓+1↗

②依题意得←=4      ↓=2        ■=5      ↗=9

                则原题得↙■0+↘↓→=↙*5*0+↘*2*→

                                                =↘*2*→

                                                =2*↘→

                                                =270

③依题意得←=（4↓）=（2■）=（5↗）=9       求↙■0+↘↓→的值

                      可得↙■0+↘↓→=0+↘↓→

                                   由题可得5↗=9 

                                           则

可得↘由 ↗顺时针旋转90°得

则将

                                            

顺时针旋转90°

得到图形不相符合，则原假设不成立，原题无解
