a, 245 + (- 2023) + (- 45) + 23

= 245 - 2023 - 45 + 23

= ( 245 - 45 ) - ( 2023 - 23 )

= 200 - 2000

= -1800

b, (- 1986) + 2478 + 986 + (- 1478)

= - 1986 + 2478 + 986 - 1478

= ( - 1986 + 986) + ( 2478 - 1478)

= - 1000 + 1000

= 0

c, (- 2024) + 1976 + 2024 + (- 976)

= - 2024 + 1976 + 2024 - 976

= ( - 2024 + 2024 ) + ( 1976 -976 )

= 0 + 1000

= 1000

d, ( - 415 ) + 248 + (- 85 ) + 52

= - 415 + 248 - 85 + 52

= ( 248 + 52 ) - ( 415 + 85 )

= 300 - 500

= -200

e, (- 17) + ( - 196) + 296 + 117

= - 17 - 196 + 296 + 117

= ( 296 - 196) + ( 117 - 17)

= 100 + 100

= 200

f, 245 + ( - 1976) + 55 + 976

= 245 - 1976 + 55 + 976

= ( 245 + 55) - ( 1976 - 976)

= 300 -1000

= - 700

g, ( - 1798) + 24 + 798 + ( - 1924)

= - 1798 + 24 + 798 - 1924

= ( - 1798 + 798) - ( 1924 - 24) 

= -1000 - 1000

= -2000
