數學題.........

( - 1 8 ) + ( - 6 ² ) ÷ ( - 3 ) ²
= -18 + (36÷9)
= - 18 + 4
= -14

The answer is~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~-22

( - 1 8 ) + ( - 6 ² ) ÷ ( - 3 ) ²
= - 1 8 + - 36 ÷9
= - 1 8 + -4
= -22

-18+(-36÷9)
=-18+(-4)
=-18-4
=-22

22

-18 + [ - ( 6 ² ) ]÷ ( - 3 ) ²
= -18 - ( 36 ÷ 9 )
= -18 - 4
= - 22
═

( - 1 8 ) + ( - 6 ² ) ÷ ( - 3 ) ²

= - 1 8 - 36 ÷ 9

= - 1 8 - ( - 4 )

= - 1 8 + 4

= - 14

應該係咁．．．（＞口＜）ｖ

( - 1 8 ) + ( - 6 ² ) ÷ ( - 3 ) ²
= -18 - 36 ÷3
= - 18//

sor......( - 1 8 ) ( - 6 ² ) ÷ ( - 3 ) ²= -18 -(36÷9)= - 18 - 4= -22//

-18 -36 ÷ 9
-18- 4
=-22

(-18)+(-6²)÷(-3)²
=(-18)+(-36)÷9
=(-18)+(-4)
=-22

( - 1 8 ) + ( - 6 ² ) ÷ ( - 3 ) ²
= (-18) + 36÷9=4-18
=-14
