40% of 220 × 15 ÷ 20 = ?
[5 X {(52 X 5) - 10} + 50 of 20] = ?
315 ÷ 9 + 23 × 3+ 22 = ?× √441
375% of 320 - 80% of 40 ÷ √256 = ?
(112 × 4) ÷ 16 + 484 = (?)3
25% of 440 + 88 X (1/2)2 - 28 = 8 X ?
(43/10) + (4.2/1.2) - (2.7/3) = (?/4) + (2.7/6.0)
125 ÷ 5 + 14 × 4 = ? + 72 ÷ 4 – 35
18 + 28÷ 4 - 14 = ? - 35
...√529 + √64 + 92 = ?
