✔ 最佳答案
(-5)除(+5)+(-9)x(+9)= (-1) + (-81)
= - 82
[(-8)+18]除(-5)+(-8)
= (+10) 除(-5) + (-8)
= (-2) + (-8)
= - 10
Comment:
[(-8)+18] 是 +10, 不是 -10
$12334 (譯英文)
Twelve thousand three hundred and thirty-four dollars
Comment:
thirty-four 正確英語有 hyphen, dollars 這個字不可以 missing

(-5)除(+5)+(-9)x(+9)=-1+(-9)x(+9) =-1+(-81)=-1-81=-82 [(-8)+18]除(-5)+(-8)=(-10)除(-5)+(-8)=2+(-8)=2-8=-6 $12334=twelve thousand three hundred and thirty four(do not put 'and' in the middle)
