The absolute value of a is - A, a may be positive, 0 and negative? Explain the reason! Explain why!

The absolute value of a is - A, a may be positive, 0 and negative? Explain the reason! Explain why!

A can only be negative, and 0, not negative
Because the absolute value of any number is positive
Your absolute value of a is - A, so a is negative to get a positive number
Then there is no positive and negative difference between 0 and 0

Write all integers whose absolute value is less than 5 and represent them on the number axis. Is there the smallest positive number and the largest negative number? Why?

All integers with absolute value less than 5 are + 1, - 1, + 2, - 2, + 3, - 3, + 4, - 4,0
As for the expression on the number axis, just mark a dot on these numbers!
Is there the smallest positive number and the largest negative number? Why?
No, because there are countless positive and negative numbers, they have no maximum and minimum values! Only the largest negative integer is - 1, the largest positive integer is 1!
Please, my little brother, give me some points,

If there are two negative numbers, the absolute value?

If there are two negative numbers, the number with larger absolute value will be smaller!
