jika diketahui r= -84, s =7, t = -26, dan u =91, maka tentukan hasil dari:
-t + u - r : s
-t + u - r : s

Jawaban:
-t + u - r : s
= -(-26) + 91 - (-84) : 7
= 26 + 91 - (-12)
= 117 + 12
= 129
Penjelasan dengan langkah-langkah:
r = -84
s = 7
t = -26
u = 91
Maka
= -t + u - r : s
= -(-26) + 91 - (-84) : 7
= 26 + 91 + 84 : 7
= 26 + 91 + (84 : 7)
= 26 + 91 + 12
= (26 + 91) + 12
= 117 + 12
= 129
∴ Jadi, hasilnya adalah 129
