Four fours!

Warm up:

Place operation symbols between the ones to make the equations true.  (Use the four operations and parentheses.)

1    1    1    1    =     0

1    1    1    1    =     1

1    1    1    1    =     2

1    1    1    1    =     3

1    1    1    1    =     4


Work out:

4   4   4   4  =  0 

4   4   4   4  =  1 

4   4   4   4  =  2 

4   4   4   4  =  3 

4   4   4   4  =  4 

4   4   4   4  =  5 

4   4   4   4  =  6 

4   4   4   4  =  7 

4   4   4   4  =  8 

4   4   4   4  =  9 

4   4   4   4  =  10
