a) 2,4 - 0,72 -6,173 -1,4 +0,173 + 0,72 = 1 -6 = -5
( 2,4 - 1,4 = 1 -0,72 +0,72= 0 -6,173 +0,173 = -6)
b) -3,14 +2,6 -6,27 +2,14 +1,4 +1,27 = 1 +4 -5 = 0
( -3,14 + 2,14 =1 2,6 + 1,4 = 4 -6,27 + 1,27 = -5 )
c) -7,2 +1,42 -12,13 +0,58 -2,8 +2,13 = 10 + 2 - 10 = 2
( -7,2 -2,8 = 10 1,42 +0,58 =2 -12,13 + 2,13 = -10 )
