hum U-U

1. 3(2) - 3(2) + 12 - 2!
2. -5 + 3!​

Jawaban:

1. 3(2) - 3(2) + 12 - 2!

(3×2) - (3×2) + 12 - (2×1)

6 - 6 + 12 - 2

0 + 12 - 2

12 - 2

= 10

2. -5 + 3!

(-5) + (3×2×1)

(-5) + (6×1)

(-5) + 6

= 1

Jawaban :

1.

3(2) - 3(2) + 12 - 2! =

= (3 × 2) - (3 × 2) + 12 - (2 × 1)

= (3 + 3) - (3 + 3) + 12 - 2

= 6 - 6 + 12 - 2

= 0 + 12 - 2

= 12 - 2

= 10

______________

2.

-5 + 3! =

= -5 + (3 × 2 × 1)

= -5 + (6 × 1)

= -5 + 6

= 6 - 5

= 1
