1) U' R' F' R S R' F R S' U M2can you translate these two algs for me?

I don't understand commutators notation at all...

1) [U' : R' F' R, S] M2

2) M2 [U' : S, R' F' R]

2) M2 U' S R' F' R S' R' F R U

So,

[A, B]= A B A' B'

For example: [R, U]= R U R' U'

[R U R', D']= R U R' D' R U' R' D

[A : B, C]= A (B C B' C') A'

For example: [F : R U2 R', D']= F (R U2 R' D' R U2 R' D) F'
