Question

can you please solve this _/\_
I will follow you......really yaar......please please☺☺☺☺​

Answer 1

(-10)+3= (-7) Observation- Result is an integer

(-75)+18= (-57) Observation- Result is an integer

27+(-27)= 0 Observation- Result is an integer

(-20)+0= (-20) Observation- Result is an integer

(-35)+(-10)= (-45) Observation- Result is an integer

Answer 2

Answer

(i)

17 + 23 = 40

Observation :- A positive Integer

Explanation :- As a Integers are the counting numbers Including there negative and 0

So by above 40 is a Integer and also a positive number

Hence a Positive Integer

(ii)

(-10) + 3

= 3 - 10

= -7

As from above it is a Integer and Negative

Hence a Negative Integer

(iii)

(-75) + 18

= 18 - 75

= -57

Hence a Negative Integer

(iv)

19 + (-25)

= 19 -25

= -6

Observation :- a Negative Integer

Explanation :- As we know a Integers are whole number with their Negatives

As -6 is a Negative of 6 (a whole number)

Hence a Negative Integer

(v)

27 + (-27)

= 27 - 27

= 0

As zero is neither Negative nor Positive

Hence a Integer

(vi)

(-20) + 0

= -20 [ As the additive Property of zero say When it's added to any number the results is the same number]

Hence a Negative Integer

(vii)

(-35) + (-10)

= -35 - 10

By taking (-) as common

= -(35 + 10)

= -(45)

= -45

Hence a Negative Integer
