1. Periksa dan bacalah soal-soal terlebih dahulu sebelum anda
mengerjakan.
2. Kerjakan soal sesuai perintah.
3. Tulislah proses dalam mengerjakan soal.
SOAL – SOAL :
1. Carilah hasil penjumlahan berikut !
a. ( 5 + 3 ) + ( -6 ) + (-1 )
c. -6 + (7 + 1 ) + (-2 )
b. ( -4 + 3 ) + ( -5 ) + 2
d. 10 + (-20 ) +0 + 4
2. Diberikan a = 4, b = -6, c = 7, d = 13, dan e = 15.
Hitunglah :
a. (a + b ) – (c + e)
c. (b –a ) + c
b. ( a + e) – c
d. (c – d) – a
3. Hitunglah perkalian tersebut !
a. [ 4 x (-3) ] x (-5 )
d. 4 x [ (-3) x (-5 )]

b. 2 x (3 + 4)
e. (2 x 3 ) + ( 2 x 4 )
