Question

1992+(-53)+158+(-247)+(-1592)

Answer 1

=1992 - 53 + 158 - 247 - 1592

=( 1992 - 1592 ) - [ 53  + 247 ] + 158

= 400 - 300 + 158

=100 + 158 = 258

Answer 2

1992 + ( - 53 ) + 158 + ( - 247 ) + ( - 1592 )

= 1992 + ( - 1592 ) + ( - 53 ) + ( - 247 ) + 158

= 400 + ( - 300 ) + 158

= 100 + 158

= 258

Answer 3

1992 + ( -53 ) + 158 + ( -247 ) + ( -1592 )

= 1992 - 53 + 158 - 247 - 1592

= ( 1992 - 1592 ) - ( 53 + 247 ) + 158

= 400 - 300 + 158

= 258
