Q.

1 + 2 - 3 + 4 - 5 + 6 - 7

= ?

Dengan cara ✔✔​

Jawaban:

Pengoperasian Bilangan

1 + 2 - 3 + 4 - 5 + 6 - 7

= 3 - 3 + 4 - 5 + 6 - 7

= 0 + 4 - 5 + 6 - 7

= 4 - 5 + 6 - 7

= -1 + 6 - 7

= 5 - 7

= -2

1.) 1 + 2 - 3 + 4 - 5 + 6 - 7

= ( 1 + 2 ) - 3 + 4 - 5 + 6 - 7

= 3 - 3 + 4 - 5 + 6 - 7

= ( 3 - 3 ) + 4 - 5 + 6 - 7

= 0 + 4 - 5 + 6 - 7

= ( 0 + 4 ) - 5 + 6 - 7

= 4 - 5 + 6 - 7

= -( 5 - 4 ) + 6 - 7

= (-1) + 6 - 7

= ( 6 - 1 ) - 7

= 5 - 7

= (-2)
