3rd layer Solved- Rubik Cube

There are some rules(formulae)
At first you need to make a plus sign in the third layer.
Plus = F R U R' U'F'
( you have to apply this formula until you make a plus sign, maybe twice, thrice or once )
THEN
Match centres = R U U R' U' R U' R'

Place Corners= L U R U' L' U R' U'

Last Step= R U U R' U' R U' R'
L U U L' U L U L'
(you have to apply all these formulae until you make the mentioned position, maybe twice, thrice or once. )
Thank you ..
