Answer 1

4.

(a) |-10+24|:(-7)=|14|:(-7)=14:(-7)= - 2

(c) ||-2|×(-6+2)+5×(-2)|:(-3-1-2)=

=|2×(-4)+(-10)|:(-6)=

=|-8-10|:(-6)=

=|-18|:(-6)=

=18:(-6)=

= -3

(e) -27:|4:(-2)-15:(-3)-|14:(-7)-4||=

= -27:|-2+5-|-2-4||=

= -27:|3-|-6||=

= -27:|3-6|=

= -27:|-3|=

= -27:3=

= -9

5.

(a)(-24):(-4)+(-6):2=6+(-3)=6-3=3

(c) [(-7-9):(-4)+(+6)]:5=[(-16):(-4)+6]:5=(4+6):5=10:5=2

(e)(-8+2)×(-3):(-2)+(-8):2=(-6)×(-3):(-2)+(-4)=18:(-2)-4= -9-4= -13
