ruby - Combining rand() numbers -

i'm attempting combine few random numbers. numbers supposed represent dice.

for example, want roll dice 5 times , following results: 4 2 1 4 6.
these individual numbers want combine 42146.

this might simple question apologize i'm still new ruby.

i'm generating numbers between [1,6] through this:

number = 1 + rand(6) 

1.upto(5).map { rand(1..6) }.join.to_i 

• 1.upto(5) give enumerator 5 elements
• map { rand(1..6) } map random number between 1 , 6 each of above elements
• join concatenate elements of got far
• to_i transform above result string integer
