Answer 1

1; - 7264 + (1543 + 7264)

= - 7264 + 1543 + 7264

= (-7264 + 7264) + 1543

= 0 + 1543

= 1543

2; (14497) - 144

= 14497 - 144

= 14353

Answer 2

3; (-145).(18145)

= -145.18145

= -2631025

4; 111 + (-11 + 27)

= 111 + 16

= 127

Answer 3

5; (27 + 514) - (486 - 73)

= 27 + 514 - 486 + 73

= (27 + 73) + (514 - 486)

= 30 + 28

= 58

6; (36 + 79) + (145 - 79 -  36)

= 36 + 79 + 145 - 79 - 36

= (36 - 36) + (79 - 79) + 145

= 0 + 0 + 145

= 145

Answer 4

7; 10.[12 - (-9 - 1)]

= 10.[12 - (-10)]

= 10. [12 + 10]

= 10.22

= 220

Answer 5

8; (3829 + 43) - (43 + 38)

=  3829 + 43 - 43 - 38

= (3829 - 38) + (43 - 43)

= 3791 + 0

= 3791

Answer 6

9; 271.[(-43) + 271 - (-17)]

= 271 . [ -43 + 271 + 17]

= 271 . [228 + 17]

= 271.245

= 66395

Answer 7

10; -144 - [29(144) - (+144)]

= - 144 - [ 29.(144) - 144]

= - 144 - 29.144 + 144

= - 144 + 144 - 29.144

=  - 29.144

= - 4176

= - 144 - 29

= - 173
