Let's know that a and B are opposite to each other, C and D are reciprocal to each other, and the absolute value of X is 5, and find the value of X - (a + B + CD)

Let's know that a and B are opposite to each other, C and D are reciprocal to each other, and the absolute value of X is 5, and find the value of X - (a + B + CD)

a. B is opposite to each other, a = - B, a + B = 0
c. D is reciprocal, C = 1 / D, CD = 1
|x|-(a+b+cd)
=5-(0+1)
=5-1
=4

Given that a and B are opposite to each other, C and D are reciprocal to each other, and the absolute value of X is 5, find the value of CD + A + B - X

c. If D is reciprocal to each other, then CD = 1;
a. If B is opposite to each other, then a + B = 0;
So the original formula is 1 + 0-5 = - 4

It is known that a and B are opposite to each other, C and D are reciprocal to each other, the absolute value of M = 5, X-Y = - 3,
It is known that a and B are opposite to each other, C and D are reciprocal to each other, the absolute value of M = 5, X-Y = - 3,
I just want to know, X-Y = - 3, x + y =?,
How to use the method of filling in brackets to know? The teacher didn't quite understand at that time. How to add brackets to get the answer. I'm poor at math

a+b=0 cd=1
|m|=5 x-y=-3
What's the relationship between X + y =? Z and ABCD?

If the sum of two rational numbers is greater than any of the addends, then these two numbers ()
A. It's all negative
B. A positive number, a negative number
C. All positive numbers
D. None of the above is true

C
According to: Grade 7 mathematics 2.1 ~ 2.2 level test
3. Judgment question: ((fill in t for "right" and F for "wrong")
(6) If the sum of two rational numbers is greater than any of the addends, then both numbers are positive. (T)
