Question

(27-514)-(486-73)

Answer 1

= 27 - 514 - 486 + 73

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

= 100 - 1000

= -900

Answer 2

( 27 - 514 )-(486-73)

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

= 1000 -100

= 900

Answer 3

\(\left(27-514\right)-\left(486-73\right)\)

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

\(=\left(27+73\right)-\left(514+486\right)\)

\(=100-1000=-900\)

Answer 4

(27-514)-(486-73)

=(-487)-413

= -900

Answer 5

(27-514)-(486-73)

= 27 - 514 - 486 + 73

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

= 100 + -1000

= -900
