✔ 最佳答案
致回答者: 神風亨其實呢條數好多高中生,甚至大學生都計錯
6÷2(3) , 係唔等於 6÷(2*(3))
只有括號入面ge野會係先做 , 其他所有都係由左計到右
所以係計左 6除2先 再乘 3 , 所以答案是9
之所以計錯1 , 我諗係因為中學成日要將出面ge野乘入去
除如 a(b+c) = ab+ac
令人會以為6÷2(3) 要將2乘入去3先 答案 = 1
但如果是這樣 原本 6÷2(1+2) 先乘入去的話會變成 6÷2+4 = 7
6÷2(1+2) 不等於 6÷2(3) ??
所以這種做法是錯的
正確是由左做到右
PS : 如果前面冇野 2(1+2) 同 2(3) 用乘入去ge方法計出黎係一樣的

6÷2(1＋2) 等於?
6÷2(1＋2)
= 6÷2=3
=(1+2)=3
6÷2(1＋2)
=3 3
e.g. "3f" is a Algebra,
"33" =3X3
ANS is "9"
6÷2(1＋2)
= 6÷2=3
=(1+2)=3
6÷2(1＋2)
=3 3
e.g. "3f" is a Algebra,
"33" =3X3
ANS is "9"

Many people said that the answer is 1. But the actual results should be 9.
Just you know that the steps of a calculation. Then, you will get the result.
First, we calculate the bracket parts.
6÷2(1+2)
=6÷2(3)
Then, we should calculate from left to right.
6÷2(3)
=3(3)
=9
And you get the result of 9.
