Question

this question is so difficult​

Answer 1

Answer: O and A = 0

               C and L = variable, where C + L < 10

               D and S = variable (dependent on C and L)

Step-by-step explanation:

O and A are definitely 0 because 0 + 0 is 0

C and L can be anything but their sum should be less than 10 as O is 0

S and D are dependent on C and L respectively

For example: If we take C =1 and L = 3

then D = 4 and S = 2
