42 + 52% of 300 - ?% of 200 = 88
[{70 + (40 - 22) ÷ 3} ÷ 4] = ?
Find the value of
48 ÷ 3 of 6 of [9 ÷ 3 of (12 ÷ 4 + 6)] + (7.5 ÷ 2.5 + 2)
33 × ?2 – 6 × 5 = 3270
Simplify: 6(x³ − 2x² + 3x) − (x³ + 2x − 3).
26 X √25 + 15 - 80% of 120 = ?2Â
What value should come in place of the question mark (?) in the following question?
1250 − ( 320 + 180 ) × ...

4261 + 8234 + 2913 + 8217 + 6283 + 4172 =?
245 + (45 ÷ 3 + 5) × 6 - 125 = ?
