If the correct sum of two numbers is negative, then at least one of the two numbers is negative and the absolute value of the sum of two rational numbers is equal to the absolute value of the two numbers
1Correct.2incorrect:|-2 3|=2+3=5;|-2+3|=|1|=1
The reciprocal of the rational number A is 1|A. If the absolute value of a number is equal to the opposite number of the number, then the number is negative or zero. Choose a right
The next one is zero.
There's a zero behind. There's no countdown.
