(14.98% of 319.99) - 7.998 = √?
? = 49.99² ÷ (1.98⁵ + 8.01 × 89.91) + 75.15% of (263.89 × 49.11)
[15.87% of 599.97 + 40.08 × ?] ÷ 4.04 = 8.082.02
60.22 of 449.98% + 459.99 ÷ 23.18 = ?
√2703.88 × √784.15 – 26² = ? - (34.85)²
139.88% of 145.09 + 721.93 ÷ 38.13 +? = 29.14 * 8.18
11.69% of 499.78 + (2.89 × 39.76) = ?
431.98 + ? – 15.04 = 864.93 – 368.01
