According to J.B. Helmont “ water was the sole nutrient of Plants”.
(13)2 - 3127 ÷ 59 = ? x 4
(1/8) × (256 × 2)/(8 × 4) + ?3 = 1730
[3/5 of (31 + 44) – 10] ÷ 7 = ?
(5⁴) 5 × (25³)³=?
36% of 540 – (45% of 7300) ÷ 75 =?
198 + 105 - 215 = ?
15(2/9) + 11(2/9) + 17(1/9) + 13(4/9) = ?
6269 + 0.25× 444 + 0.8× 200 = ? × 15
...√3598 × √(230 ) ÷ √102= ?
