52000 ÷ 40 ÷ 65 × 30 = ? - ?400
(52000 ÷ 40) ÷ 65 × 30 = ? - 20
(1300 ÷ 65) × 30 = ? - 20
20 × 30 = ? - 20
600 = ? - 20
? = 620
12.5 × 3.2 × 8.8 = 352
41% of 600 - 250 = ? - 77% of 900
? 246 - 250 = ? - 693
? 246 -250 + 693 = ?
? ? = 689
As per the BODMAS rule, Addition and subtraction can be treated on same priority (from left to right) when they are in consecutive order.
65% × 700 + 14 - 9 × 3 65 × (700/100) + 14 - 27 455 + 14 - 27 = 442
