Find the balance after buying
3 2 persons generously
donated RM3 000 each. the bookcases.
2 × RM3 000 − RM1 200 =

Step 1 Step 2

RM3 0 0 0 5 10
× 2 RM6 0 0 0
RM6 0 0 0 – RM1 2 0 0
RM4 8 0 0

2 × RM3 000 − RM1 200 = RM4 800
RM1 200 will be used
to buy bookcases. The balance after buying the
bookcases is RM4 800.

4 (100 − 20) × 3 = 5 (300 − 25) × (24 − 11) =

Step 1 Step 2 (300 − 25) × (24 − 11) 2 1

1 0 0 8 0 = 275 × 13 × 2 7 5

– 2 0 × 3 = 3 575 1 8 2 5
8 0 2 4 0
+ 2 7 5 0

(100 − 20) × 3 = 240 3 5 7 5

Operations in the brackets (300 − 25) × (24 − 11) = 3 575
must be solved first.

60 − 17 × 3 = 129
The number sentence above is wrong.

Solve these.

a 16 − 2 × 5 = b 32 × 7 − 102 = c 900 − 215 × 4 =

d 24 139 − 916 × 8 = e (407 − 93) × 6 = f 809 × (82 − 56) =
g (3 010 − 59) × (200 − 195) = h (7 103 − 2 016) × (500 − 431) =
