142 + 233 + ?2 – 301 = 450 + 65
((12+12+12+12)÷4)/((8+8+8+8+8+8)÷16) = ?
(190/38) × (55/5) + (306/18) = ?
32% of 4080 + 24% of 455 = x% of 4000
The value of 11 × 11 + 11 ÷ 11 – 11 × 11 + 11 + 11 × 11 – 11 – 11 × 11 is:
(√ 196 x √ 36 x √ 100) = ?% of 200
If x + y + 3 = 0, then find the value of x3 + y3 – 9xy + 9.
24% of 150% of 500 + 140 = ? × 8
