[(82× 162)/12] - 28 = ?
[(82× 162)/12] - 28 = ? => ? = 1107 - 28 => ? = 1079
(120 × ?)/(36 × 0.2) = 200
?2 = √20.25 × 10 + √16 + 32
20 × 224÷ 16 – 50 = ? + 100
...72% of 400 – 23% of 1020 = 120% of ?
√11025 x √5625 - (50)² = (?) + (73)²
4567.89 - 567.89 - 678.89 = ?
36 x 3.6 ÷ 0.5 ÷ ? = 64
56 x 8 – 65% of 40 = ? + 14 x √625
192.251 + 326.233 + 125.021 + 19.273 = ?
110 ÷ 5.5 + (?)3 ÷ 12 = 20(2/3)
