Explicación paso a paso:

a) 4+ (-6)  = 4 - 6 = 2

b)3 + (-10)  = 3 - 10 = -7

C)2 + (-5) + 3  = 2 - 5 + 3 = -3 + 3 = 0

d) - 15 + 32 - 19 - 12 = 17 - 19 - 12 = -2 - 12 = -14

e) 21.77 + 12.3 - 45.76 = 34.07 - 46.46 = -11.69

f)890+ (-1532) + (-1820) =  890 - 1532 - 1820 = -642 - 1820 = -2462

g)39.8 + (-12.40) + (-39.8)  = 39.8 - 12.40 - 39.8 = 27.4 - 32.8 = -12.40

h)-40+(-25)+(-12)+38+(-15)  = 40 - 25 - 12 + 38 - 15 = 15 - 12 + 38 -15 = 3 + 38 -15 = 41 - 15 = 26

i)25.75+(-29.20) + 148  = 25.75 - 29.20 + 148 = -3.45 + 148 = 144.55

j)10+ (-10) + (-10)+ (-10) ​= 10 - 10 - 10 -10 = 0 - 10 - 10 = -20
