Question

Find the value of the following:
a) (-27) + (-41)

b) (-37) - (+16)

Answer 1

$\huge\bold\red{Answer}$

$a) \: ( - 27) + ( - 41) = - 27 - 41 = - 68 \\ \\ b) \: (- 37) - ( 16) = - 37 - 16 = - 53$

Answer 2

Given:

a) (-27) + (-41)

b) (-37) - (+16)

To Find:

Find the value of the following:

Solution:

We should know the additive and multiplicative rules before solving the question,

Additive rules are those rules when we add different numbers which are positive and negative or either one then what will be the sign of the final result, which are as follows,

(-)+(-)=(-)

(+)+(+)=(+)

(-)+(+)=(-) if (-)<(+)

(-)+(+)=(+) if (+)<(-)

Multiplicative rules are those rules when we multiply different numbers which are positive and negative or either one then what will be the sign of the final result, which are as follows,

(-)*(-)=(+)

(+)*(-)=(-)

(+)*(+)=(+)

So using these rules solve the given equations, which will be

(a)

$=(-27)+(-41)\\=-27-41\\=-68$

(b)

$=(-37)-(+16)\\=-37-16\\=-53$

Hence, the values of the given equation are -68 and -53 respectively.
