Ayudenmeeeeeeeeeeeeeeee xfaa

Answer 1

1) -4(8:-4+3x4)= -4 (-2+12) = -4x10= -40
2) -12:(-4x2-2x-2)= -12: (-8+4)= -12:-4= 3
3) 5 (-16:8-3x8)= 5(-2-24)= 5x-26= -130
4) (-10:5+2x-3)-15= (-2+-6)-15= -8-15= -23
5) -28:(-3-(9-4)+1)= -28: (-3-5+1)= -28:-7= 4
6) -45:(-2+12:-4)+12= -45:(-2-3)+12= -45:-5+12=9+12= 21
7) -(-24:-8)+5= +24:-8+5= -3+5= 2
8) -36:(-8:-2+12:6)= -36:(4+2)= -36:6= -6
9) 3x-8+-3x-2= -24+6= -18
10)12:-4= -3
11) -5x(-1)-(-2)x(-5)= 5+2x-5= 5+-10= -5
