1. Operasi darab yang melibatkan integer: 2. Operasi bahagi yang melibatkan integer:
Operation of multiplication involving integers: Operation of division involving integers:
• (+a) × (+b) = a × b • (+a) ÷ (+b) = a ÷ b
• (+a) × (–b) = –(a × b) • (+a) ÷ (–b) = –(a ÷ b)
• (–a) × (+b) = –(a × b) • (–a) ÷ (+b) = –(a ÷ b)
• (–a) × (–b) = a × b • (–a) ÷ (–b) = a ÷ b

F Lengkapkan operasi yang berikut dengan tanda operasi dan nilai yang betul. TP 3 ARAS R
Complete the following operations with the correct operation signs and values.

Contoh Contoh Contoh Contoh

+8 × (+2) +9 × (–5) –2 × (+13) –4 × (–11)
= + (8 × 2) = – (9 × 5) = – (2 × 13) = + (4 × 11)

= 16 = –45 = 44
= –26
1. +11 × (+5) 3. +6 × (–7) 5. –8 × (+9) 7. –6 × (–12)

= + (11 × 5) = – (6 × 7) = – (8 × 9) = + (6 × 12)
= 55 = –42 = –72 = 72

2. 3 × (+7) 4. 12 × (–5) 6. –16 × 10 8. –13 × (–5)
= + (3 × 7) = – (12 × 5) = – (16 × 10) = + (13 × 5)
= 21 = –60 = –160 = 65

G Lengkapkan operasi yang berikut dengan tanda operasi dan nilai yang betul. TP 3 ARAS R
Complete the following operations with the correct operation signs and values.

Contoh Contoh Contoh Contoh
+77 ÷ (+7) +24 ÷ (–6) –63 ÷ (+9) –12 ÷ (–3)

= + (77 ÷ 7) = – (24 ÷ 6) = – (63 ÷ 9) = + (12 ÷ 3)
= 11 = – 4 = –7 = 4

1. +150 ÷ (+15) 3. +27 ÷ (–9) 5. –42 ÷ (+7) 7. –54 ÷ (–9)
= + (150 ÷ 15) = – (27 ÷ 9) = – (42 ÷ 7) = + (54 ÷ 9)

= 10 = –3 = –6 = 6

2. 240 ÷ (+16) 4. 64 ÷ (–4) 6. –108 ÷ 12 8. –121 ÷ (–11)
= + (240 ÷ 16) = – (64 ÷ 4) = – (108 ÷ 12) = + (121 ÷ 11)
= 15 = –16 = –9 = 11
