  1. |-1/2| + (-2/3) : |-4| + (23/2019)^{0}
    = 1/2 + (-2/3) : 4 + 1
    = 1/2 + (-1/6) + 1
    = 3/6 + (-1/6) + 1
    = 1/3 + 1
    = 1/3 + 3/3
    = 4/3
     

  2. |-1/2| + (-2/3) : |-4| + (23/2019)^0
    = 1/2 + -2/3 : 4 + 1
    = 1/2 + -1/6 + 1
    = 3/6 + -1/6 + 6/6
    = 2/6 + 6/6
    = 8/6
    = 4/3
