Note: Operations within the bracket are to be carried first.
Brackets are of 4 types.
= 24 – [12 – {8 – (9 – 2 – 3)}]
= 24 – [12 – {8 – 4}]
= 24 – [12 – 4]
= 24 – 8
= 16
i) 1.6 x 20 x 12 + 30 x 2
ii) 2.21 ÷ 0.7 = ? + 5.5
iii) 4545 ÷ 50 ÷ 5 = ?
i) 35% of 495 + ? = 250
ii)
iii) 30% 150 + ? of 300 = 40 % of 450
i) (19.7)^{5} ÷ (19.7)^{4} =?
ii) 23^{10.5} x 23^{5.1} ÷ 23^{1.2} = 23^{?}
