Question

Can you get a sum of 30 by adding 1+3+5+7+9+11+13+15 in 5 squares? You can use use any number more than once.

Answer 1

1) 3! + 3! + 3! + 3! + 3! = 30
2) 3 + 5 + 7 + 9 + 3! = 30

Where 3! = 3 x 2 x 1= 6

Answer 2

No we cant find the sum by adding 1+3+5+7+9+11+13+15 in 5 squares but we can find this sum by adding factorial sign (!)

3 + 5 + 7 + 9 + 3! = 30
            Or

3! + 3! + 3! + 3! + 3! = 30

Here 3! mean = 1 × 2 × 3
                    = 6
