Hey there! It looks like you're working on some math problems. Let's solve them together! Here are the answers:

a) -34 - {-74 + [-58 + (+72) + (-21)] + (-14)} + (54) = -34 - {-74 + [-58 + 72 - 21] - 14} + 54 = -34 - {-74 + -7 - 14} + 54 = -34 - {-95} + 54 = -34 + 95 + 54 = 115.

b) -36 + {-28 - [-48 + (-50) + (+63)] + (-74)} + (+63) = -36 + {-28 - [-48 - 50 + 63] - 74} + 63 = -36 + {-28 - [-35] - 74} + 63 = -36 + {-28 + 35 - 74} + 63 = -36 + -67 + 63 = -40.

c) -80 - {-38 + [-49 + (+32) + (+27)] + (+48)} + (-36) = -80 - {-38 + [-49 + 32 + 27] + 48} - 36 = -80 - {-38 + [10] + 48} - 36 = -80 - {-38 + 10 + 48} - 36 = -80 - {20} - 36 = -80 - 20 - 36 = -136.

d) -49 - {-54 - [-25 + (-67) + (+42)] + (+83)} + (+24) = -49 - {-54 - [-25 - 67 + 42] + 83} + 24 = -49 - {-54 - [-50] + 83} + 24 = -49 - {-54 + 50 + 83} + 24 = -49 - {79} + 24 = -49 - 79 + 24 = -104.

e) -54 + {-28 + [-36 + (-20) + (+30)] + (-73)} + (-24) = -54 + {-28 + [-36 - 20 + 30] - 73} + (-24) = -54 + {-28 + [-26] - 73} + (-24) = -54 + {-28 - 26 - 73} + (-24) = -54 + {-127} + (-
