1.

-5-12=-17

(-14).14=-196

6-12=-6

2.

13-18-(-42)-15

= -5-(-42)-15

=(-5-15)-(-42)

=-20+42

=22

369-4{(-5)+4.(-8)}

= 369-4.{-5+(-32)}

=369-4.{-37}

=369-(-148)

=517

(-8)³:(-8)² +8

=-8+8

=0

[✰๖ۣۜŠɦαɗøω✰]

Bài 1 :

\(\left(-5\right)-12=-17\)

\(\left(-14\right).14=-196\)

\(6-12=-6\)

Bài 2:

\(13-18-\left(-42\right)-15=22\)

\(369-4.\left[\left(-5\right)+4.\left(-8\right)\right]=517\)\

\(\left(-8\right)^3:\left(-8\right)^2+8=0\)

Study well!!
