a. (15 – 8) – 3 dan 15 -(8-3)
b. (-12-3)-(-1) dan -12-[3-(-1)]
c. [-15-(-7)] -4 dan -15- (-7-4)
3. Hitunglah pengurangan-pengurangan berikut.
Penjelasan dengan langkah-langkah:
A. 1 )(15 – 8) – 3
= 7 – 3
= 4
2)15 -(8-3)
= 15 – 5
= 10
B.1) (-12-3)-(-1)
= -15 – (-1)
= -15 + 1
= -14
2) -12-(3-(-1))
= -12 – (3 + 1)
= -12 – 4
= -16
C. 1) (-15-(-7)) -4
= (-15 + 7) -4
= -8 -4
= -12
2) -15- (-7-4)
= -15 – (-11)
= -15 + 11
= -4
