how can the sample space of rolling a two dice 36 ? isn't it 42?

Hi, how can the sample space of rolling a two dice 36 ? isn't it 42?

it write the there is a possible to get 1,1 and 2,2 and 3,3 and 4,4 and 5,5 and 6,6
but it's for the (first die,second die),(first die,second die),(first die,second die),(first die,second die),(first die,second die),(first die,second die)

but what if it can be (second die,first die),(second die,first die),(second die,first die),(second die,first die),(second die,first die),(second die,first die)
for example (5,5) for the second die at first and first die the last,

so there is more 6 to calculate not just 36!

36+ 6 = 42

am I right or not  please give me an explanation

Getting a 5 on the first die and a 5 on the second die is the same as getting a 5 on the second die and a 5 on the first die.
