Question

If a and b are two negative integers, then state the sign of the given expressions in each of the following, if known definitely
(i) a + b (ii) a-b. (iii) axb (iv) a + b​

Answer 1

Step-by-step explanation:

1. a+b=c
2. a-b=a+(-b)=depends on which number is larger than put its sign
3. a×b=c
4. same as 1

Answer 2

Answer:

ans i . negative

ans ii . depends on greater number sign

ans ii . positive sign

ans iii . negative

Step-by-step explanation:

i = - a + ( -b )

= -a - b

depends on greater number sign since both are negative add and put negative sign to sum

ii = - a - (-b )

= -a + b

depends on greater number sign

iii = -a × -b

positive sign because we should multiple the signs

iv = refer answer i it's just the same question
