The series is: 36 + 12 = 37 37 – 22 = 33 33 + 32 = 42 42 – 42 = 26 26 + 52 = 51 51 – 62 = 15
1885 ÷ 64.98 + 7.29 + ? = 69.09
√3970 × √730- √2400 =?
√10404 + √9604 - ∛1728 - ∛42875 = ?
3.2% of 500 × 2.4% of ? = 288
√144 × √121 + 25% of 600 = ? + 256
862 - 37 – ? = – 432
436 × 794 – 68210 =? + 85730
1/5 of 6/3 of 3/2 of 1966 = ?
3% of 842 ÷ 2% of 421 = ?
654.056 + 28.9015 × 44.851 – 43.129 = ?
