M A D
B E
-------
M A D
R A E
-------
A M I D

• For sure E=1 as MAD*E=MAD,
  M+A=M carry of 1will be generated so A=9 and hence R=8
  And so you can try for value of B and M that will give R as 8,so M=2 and B=3
  Then I=0 as A+E=10
  Finally trying for D wll get its value as 7.

  is the correct answer....

• btw the question is not written in order...
  
  M A D
  * B E (Its a multiplication * wont be in question)
  ---------
  M A D
  R A E 0
  ------------
  A M I D
  
  E=1*MAD=MAD 1st step
  
  B*D=(sth)1 cuz B*D=(sth) E and E=1 so B/D are 3/7 (dont know which one is which in this step)
  
  now possibilities
  
  if(B==3){
  if(A==4){
  B*A=3*4=12+2=14 // (+2 cuz carry is 2 since 3*7=21) (B*A must give (sth)A in this case 14=(sth)4)
  }
  if(A==9){
  B*A=3*9=27+2=29
  }
  }
  if(B==7){
  B*A=7*8=56+2=58
  }
  
  So...A=4||A=9||A=8
  
  
  3rd step in addition M+A=M
  so...we conclude there is a carry in this step...
  cuz suppost M=3 and A=4 so... M+A can never give M so the number M+A must be greater than 10 Eg. is M=3 from addition we should get 13
  
  suppose A=9 so B=3 and D=7
  
  we know E=1
  carry 1 from previous addition
  so possibilities for M are
  if M==1
  9+1+1=11
  
  if M==2
  9+1+2=12
  
  if M==3
  9+1+3=13
  ...
  ...till M=9
  (last digit has to be M)
  but 0/1/3/7/9 are already known so possibilities for M are 2/4/5/6/8 (I=0 since A+E=9+1=10)
  
  Now last step in addition R+carry=A
  so possibility for carry in this step is just one i.e 1 cuz from last step M+A gives max 9+9=18(just example)
  so R+1=9
  so R=8
  
  remaining digits 2/4/5/6
  
  Now last Multiplication
  
  B*M=R i.e 8
  we know B=3
  so
  3*2=6+2(carry from previous step)=8 i.e R
  so M=2
  
  Now M=2, A=9, D=7, B=3, E=1
  
  2 9 7
  * 3 1
  ----------
  2 9 7
  8 9 1 X
  ---------
  9 2 0 7
