Answer 2

I am giving you straight away answers....

8) 1300 - 450 = 850.... new position of the submarine is 850 m below the sea level

9) 509,508,507....3,2,1...(excluding 0)... 474,475,476 ....(509+476) the Roman civilization lasted for about 985 years

10) temperature in afternoon-temperature in in night(2-5= -3).... the temperature during the night was -3 degree Celsius

11) 1050 + 300 = 1350 ...new position of the submarine is 1350 m below the sea level

12) melting point of Mercury - freezing point of alcohol...(-39)-(-114) = -39+114 = 75.... melting point of Mercury is 75 degree Celsius warmer than freezing point of alcohol

13) distance from Delhi = distance travelled towards west of Delhi - distance travelled towards east of Delhi.... 82 - 58 = 54.... finally she is 54 km away from Delhi

14)

a) for example... 5 + 3 = 8....8 + 2 = 10 .....10+ 5 = 15..... we find that sum of two positive integers is always a positive integer

b) for example....(-2)+(-3)=(-5).....(-5)+(-10)=(-15).... we find that sum of two negative integers is always a negative integer
