Fill in the boxes with the correct answers.

Contoh 1. –3 × (–6 + 10) 2. [–1 – (–4)] × 2
= –3 × 4 = 3 × 2
4 × (–5 + 3) Lakukan operasi
dalam tanda
= 4 × (–2) kurung dahulu. = –12 = 6
Perform operations
= –8 in the brackets 3. (–3 – 5) ÷ (–4) 4. 24 ÷ (–2 – 10)
first.
= –8 ÷ (–4) = 24 ÷ (–12)
= 2 = –2

Contoh 5. 18 + 4(–3) 6. –10 – 5 × 4

= 18 + (–12) = –10 – 20
14 + 3(–6) Lakukan operasi
darab/ bahagi = 6 = –30
= 14 + (–18) dahulu.
Perform
= –4 multiplication/ 7. 3 + 15 ÷ (–5) 8. 13 – 6 ÷ (–3)
division first.
= 3 + (–3) = 13 – (–2)
= 0 = 15

( ) × atau / or ÷ + atau / or –

I Hitung setiap yang berikut. TP 3 ARAS S
Calculate each of the following.

Contoh Lakukan operasi × 1. 3 – 18 ÷ (–3) + (–4) 2. 10 + 3 × (–5) + 8
atau ÷ dari kiri ke = 3 + 6 – 4 = 10 – 15 + 8
kanan diikuti operasi
–3 + 15 ÷ 3 – 7 = 9 – 4 = –5 + 8
= –3 + 5 – 7 + atau – dari kiri ke = 5 = 3
kanan.
= 2 – 7 Perform × or ÷ from
= –5 left to right followed by
+ or – from left to right.

3. –12 – (–4) × 5 – 10 4. –6 × 4 + 15 ÷ 3 5. –9 – 8 × 3 ÷ 6
= –12 + 20 – 10 = –24 + 5 = –9 – 24 ÷ 6
= 8 – 10 = –19 = –9 – 4
= –2 = –13
