If - A is not negative, then a must be () A. Negative B. positive C. positive and zero D. negative and zero

If - A is not negative, then a must be () A. Negative B. positive C. positive and zero D. negative and zero

According to the meaning of the question: - a ≥ 0, a ≤ 0

If rational numbers a, B, C, C are negative numbers smaller than C, a is negative numbers smaller than C, and B is positive numbers larger than zero, then simplify [a] + [b] - C

=|a|+|b|-|c|
=-a+b+c

A. 0 is not a positive number. B. 0 is an integer and even number. C. a negative third is a fraction, a negative number and a rational number
D. 0 ℃ means no temperature

D is wrong
