    a, 100 – 48 : [4^3 – 2^3. (15. 6 – 16.5)]
    = 100 – 48 : [64 – 8. (90 – 80)]
    = 100 – 48 : [64 – 8. 10]
    = 100 – 48 : [64 – 80]
    = 100 – 48 : (-16)
    = 100 – (-3)
    = 100 + 3
    = 103
    b, [159 – (36 – 35)^2019. 2 – 9]. 1001^0
    = [159 – 1^2019. 2 – 9]. 1
    = [159 – 1. 2 – 9]. 1
    = [159 – 2 – 9]. 1
    = [157 – 9]. 1
    = 148. 1
    = 148
