121 × 11 – 4 ÷ 15 + 2 121 ÷ 11 + 4 - 15 × 2 11 + 4 - 15 × 2 11 + 4 – 30 15 – 28 = -15
? = 2640 ÷ {(35% of 1240) – 170}Â
(115 × 17 × 3)/(23 × 51) + ?3 = √169
16 of 25 - 12 of 15 = ? of 5 of 11Â
119 ÷ [22 - {90 ÷ (23 - 105 ÷ (7 × 3))}] = ?
The value of 42 ÷ 9 of 6 - [64 ÷  48 x 3 – 15 ÷ 8 x (11 – 17) ÷ 9] ÷ 14 is:
(1748 ÷ 8) + 76.8 × 35 =(? × 4) + (42 × 35.5)
4.004 + 5.7(2.5 – 0.5) =?
(21 × 16 – 8) ÷ 41 = ?
48 ÷ 6 × √25 + 13 × 8 = ?
