3.5903 and 28.4097 (to 4 dp).
The two numbers that multiply to make 12 and add to make 8 are 2 and 6. When you multiply 2 and 6, you get 12 (2 × 6 = 12), and when you add them together, you get 8 (2 + 6 = 8).

1,956 different numbers can be made from 6 digits. You can calculate this by using the permutation function in a summation function, like this: Σ6k=1 6Pk = 6P1+6P2+...+6P5+6P6 What this does is calculate how many 1 digit numbers you can make from 6 digits, then how many 2 digit numbers can be made from 6 digits and adds the amounts together, then calculates how many 3 digit numbers can be made and adds that on as well etc.
