The correct one in the following statement is () A. A positive number and a negative number are opposite to each other B. the opposite number of any number is different from itself C. any number has its opposite number D. the numbers represented by two points on both sides of the origin on the number axis are opposite to each other

The correct one in the following statement is () A. A positive number and a negative number are opposite to each other B. the opposite number of any number is different from itself C. any number has its opposite number D. the numbers represented by two points on both sides of the origin on the number axis are opposite to each other

A. For example, 1 and - 2, one of them is a positive number and the other is a negative number, but they are not opposite to each other, so this option is wrong; B, 0, the opposite number is 0, so this option is wrong; C, according to the concept of opposite number, any number has opposite number, so this option is correct; D, the number represented by two points on both sides of the origin on the number axis - 5, 4, but - 5, 4 are not opposite to each other, so this option is wrong Item error. So select C

The correct one in the following statement is ()
A. - 14 and 0.25 are not opposite to each other. B. - A is negative. C. any number has opposite number. D. positive and negative numbers are opposite to each other

A. - 14 and 0.25 are opposite numbers, so the statement of option a is wrong; B, - A may be positive numbers, or 0 or negative numbers, so the statement of option B is wrong; C, any number has opposite numbers, so the statement of option C is correct; D, - 1 and 2 are not opposite numbers, so the statement of option D is wrong

Two numbers with opposite signs must be opposite to each other. Is that right?

No
For example, + 5 and - 3 are not opposite numbers, but they have opposite signs

Two numbers with opposite signs are called opposite numbers
Answer quickly, I'm in a hurry

It's not right
For example, + 1 and - 5, the correct expression is that two numbers with the same absolute value and opposite signs are opposite numbers

Two numbers with different symbols are opposite numbers
Right or wrong?
also
Two numbers that are opposite to each other must not be equal
The opposite of a positive number must be a negative number ()
All rational numbers have opposite numbers ()

Two numbers with different symbols are opposite numbers
Wrong, two numbers with different symbols and equal absolute values are opposite numbers
Two numbers that are opposite to each other must not be equal
Wrong, the opposite of 0 is still 0
The opposite of a positive number must be a negative number ()
yes
All rational numbers have opposite numbers
yes

The following statement is correct ()
A. Two numbers with different symbols are called opposite numbers B. the opposite number of an integer is a fraction C. the opposite number of a non negative number is a non positive number D. the opposite number of a number must be negative

A, e.g. + 3 and - 4 have different symbols, but they are not opposite numbers; B, the opposite number of integer 2 is - 2, and - 2 is not a fraction; C, the opposite number of non negative numbers is non positive, which is correct; D, 0 and the opposite number of negative numbers are non negative, so select C

If AB > 0, what is the symbolic relationship of AB?
Also, ab = 0, which means what is the relationship between ab?
What is the relationship between AB and 0?
Right away,

AB > 0, a and B have the same sign and are not equal to 0;
A = B, at least one of a and B is equal to 0;
ab

(1) If AB is greater than 0, then a + B is greater than 0

1.0-(-a)=a
2.ab>0
A + b > 0, so a > 0 and b > 0

Judgment: only two numbers with different symbols are called opposite numbers

Of course, the two people upstairs are right. Let me synthesize them. It's right to add that their absolute values are the same, and there is a special case of the number 0!

Numbers with opposite signs are opposite numbers. Are they right or wrong? Why?

Wrong
Only two numbers with different symbols
