Answer 2

Hello friend, here is your answer:

3) 400+399= 799

4) -308+(-182)= -308-182= -490

5) i)8 ii)176 iii)0 iv)-24

6) i)-8 => predecessor= -9,successor=-8

ii)-25 => predecessor=-26,successor=-24

iii)-100=>

predecessor=-101,successor=-99

iv)0 => predecessor=-1,successor=1

7)i)-27-(-23)

= -27+23

=-4

ii)-225-(135)

= -360

iii)-7-8-(-25)

= -7-8+25

= -15+25

= 10

iv)12-13+15

= -1+15

= 14

8)i) Sum of -5020 and 2320

= -5020+2320

= -2700

=> -709-(-2700)

= -709+2700

= 1991
