Ответ:
1) -13-27=-40
-40*4=-160
2800:(-10)²=2800:100=28
25*(-1)=-25
-160-28=-188
-188-(-25)=-188+25=-163
3) (16-(16-(16-18)))=16-16+16-18=-2
(36-(36-(36-24)))=36-36+36-24=12
-2*12=-24
2) (25-(25-(25-(25-15))))=25-25+25-25+15=15
15-(-4)²=15-16=-1
43*(-1)=-43
-1+(-43)=-1-43=-44
4) (-2-4-6-(-1-3-5))=-2-4-6+1+3+5=-3
-3*(1600-2600)=-3*(-1000)=3000
3000:(-10)²=3000:100=30
