Explanation
Addition of two negative number is always negative.
Suppose $$A$$ and $$B $$ are the absolute value of negative number $$-A$$ and $$-B$$, Then the addition number is:
$$(-A)+(-B) =-(A+B)$$ ( Where $$-(A+B)$$ is negative)

If p: when a positive integer and a negative integer are added we always get a negative integer and q: when two negative integers are added, we get a positive integer, then.
Report Question
0%
Both p and q are true
0%
p is true and q is false
0%
p is false and q is true
0%
Both p and q are false
Explanation
When we add positive integer and negative integer then it is not necessary that result would be negative integer. It can be positive integer also
For eg- $$(+8)+(-6)=2$$. Hence the p statement is false.
When we add two negative integers, we will always get negative integer.
For eg- $$(-7)+(-9)=-16$$. Hence q statement is also false
Compare and choose the appropriate sign.

Explanation
Start comparing with the numbers having greatest place value (from left) till you get an inequality.
$$4=4$$
$$3=3$$
$$2=2$$
$$9=9$$
$$5>2$$
As left value is greater than right value,
the number on the left is greater.
$$\therefore$$ $$43,29,52,280> 43,29,25,280$$
Hence correct answer is option A.

Explanation
The number line shown above represents $$-1-4$$
In above number line both arrows are going in same direction, means their will be a addition.
First arrow goes $$0$$ to $$-1$$ and second arrow goes from $$-1$$ to $$-5$$.
$$\therefore$$ $$-1+(-4)$$
$$\therefore$$ $$-1-4=-5$$
Hence, option A is correct.
