✔ 最佳答案
(-8)+6= -2(-17)+(-5)= -22
(-28)-(+12)= -40
(-20)-(-11)= -9
(+18)X(-3)= -54
(-22)X(+4)= -88
（－１．５）（＋９）＋（－６）＝ -51
（－１．４）（－７）÷（5）＝ 28/5 = 5.6
試運用1.-2.3.-4.組合出兩條結果為24的算式=
第一條：((1x-2)+(3/-4))x(-4x2) = 24
第二條：(((1+(-2) - 3 )x(-4)) / -2) x 3=24

(-8) + 6 = -2
(-17) + (-5) = -22
(-28) - (+12) = -40
(-20) - (-11) = -9
(+18) x (-3) = -54
(-22) x (+4) = -88
(-1.5) (+9) + (-6) = -13.5 + (-6) = -19.5
(-1.4) (-7) / (5) = 9.8 / 5 = +1.96
[(-2)-(+1) - (+3)] x -4 = [ (-3) - (+3)]x-4 = -6 x -4 = +24
[ 1x(-2)x(-4)]x3 = [(-2)x(-4)] x3 = [8] x3 = +24
(-17) + (-5) = -22
