Mixed operation of rational multiplication and division -3 + 5 divided by [(- 1 / 6) times (- 6)] =? It's urgent to ask for auspicious solution. If you fail the monthly exam tomorrow, you won't be alive

Mixed operation of rational multiplication and division -3 + 5 divided by [(- 1 / 6) times (- 6)] =? It's urgent to ask for auspicious solution. If you fail the monthly exam tomorrow, you won't be alive

-3+5/((-1/6)x(-6))
Let's start with the number in brackets, which is equal to - (- 6 / 6) = 1
Then calculate the molecule, - 3 + 5 = 2
So the numerator divided by the denominator 2 / 1 = 2

After learning the multiplication and division of rational numbers, Xiao Gang compiled a calculation program. When he input any rational number, it will be displayed
The result on the screen is always - 1 / 2 divided by the sum of the number entered and its absolute value. However, when he tries to enter a number, an error message appears on the screen. The number entered is (). The reason for the error message is_________ ?

0,0 cannot be divisor

1. After learning the multiplication and division of rational numbers, Xiao Gang wrote a calculation program. When he input any rational number, the result on the display screen is always half, so the sum of the input number and its absolute value. However, when he tried to input a number, the error message was displayed on the screen, and the number he entered was_____ , the reason for the error message is_____ .
2. There are several numbers, the first number is A1, the second number is A2, the third number is A3, ··, and the nth number is an. It is known that A1 = - 1 / 2. From the second number, each number is equal to the reciprocal of the difference between 1 and the number in front of them
(1) Can you tell me what A100 is?
(2) Try to calculate the value of A2008 × A2009 × A2010

1. Because the divisor cannot be 0.2, A1 = - 1 / 2A2 = 1 / (1-a1) = 2 / 3a3 = 1 / (1-a2) = 3A4 = 1 / (1-a3) = - 1 / 2a5 = 1 / (1-a4) = 2 / 3a6 = 1 / (1-a3) = 3 It can be seen that the value of an is a cycle of - 1 / 2,2 / 3,3, so A100 = - 1 / 2 (2) A2
