數學6題不會~急
Oct 1st 2013, 13:18

你好,◤唯愛◢〥楓.我之前有回答過你另一個問題.
希望這次你會記得選最佳解答,不要得到答案後付諸投票,謝謝.

第一題給的答案是錯誤的,這在我上次的回答中也有提到過.

1.(75-63)-[(-24)+(-3)]
=12-(-27)
=12+27
=39

2.(- 39)/[(- 5)-|- 8|]
=(-39)/(-5-8)
=(-39)/(-13)
=3

3. 29 * 0 /|-79|* 45 + 6 
=0+6
=6

4. (-9)*[24-8 * (-2)]
=(-9)*(24+16)
=(-9)*40
=-360

5. (-7)*[16-7 * (-2)]+210 
=(-7)*(16+14)+210
=(-7)*30+210
=-210+210
=0

6. |3+(-9)-(-1)* 2|/ (-2)
=|3-9+2|/(-2)
=|-4|/(-2)
=4/(-2)
=-2

有問題請再提問.
