Answer 1

I think it is 47184.
Solve the hundreds digit first which is 1 + 0 = 1. Then solve for the thousands digit which is 1 x 7 = 7. Then solve for tens digit whichi is 1 + 7 = 8. Then solve for for your ones which 1/2 of 8 so it is 4. Then your ones is the same as your ten thousands so the ten thousands is also 4.
