The absolute value of the product of two rational numbers is equal to the product of the absolute values of two rational numbers is it?

The absolute value of the product of two rational numbers is equal to the product of the absolute values of two rational numbers is it?


Well, I don't think both positive and negative are OK, so I don't think the options are right
The absolute value is positive, so the example (- 1) * (- 2) = 2 is right
Original formula = - 20-4 * 7 + 4 * (5 / 4) + 8 / 17 * (- 17 / 4)
=-20-28+5-2
=-20+5-30
=-45



Judgment: 1. The product of two numbers is greater than each factor () 2. The absolute value of the product of two rational numbers is equal to the product of the absolute values of the two numbers ()


1. The product of two numbers is greater than each factor (×)
2. The absolute value of the product of two rational numbers is equal to the product of the absolute values of the two numbers (√)



Integers with absolute values greater than 2.3 but not greater than 3 are______ .


Let this number be x, then 2.3 <| x | ≤ 3, | x | = 3, | x = ± 3, the integer whose absolute value is greater than 2.3 but not greater than 3 is ± 3
