2) -5.4-1.6+1.5+8.5= -7+10=3

3) -3.65-7.35+4.37+6.63=-11+11=0

4) -9.96-0.04+0.13-2.13=-10+(-2)=-10-2=-12

-5, -4, -3, -2, -1, 0, 1, 2, 3.

-4+(-3)+(-2)+(-1)+0+1+2= -10+2= -8

=====================================

420

1) -9.65-4.35+5.31+2.69=-14+8=-6

2) -2.75-1.25+6.8+3.2=-4+10=6

3) 7 19 - 7 19 + (-5 16 - 4 26) = 0+(-316-266)=-576 = 9 36= 9 12 = 9.5
