The act of holding and moving the mouse while pressing

(2500 ÷ √625) × √(42.25) = ? ÷ 4

1540 ÷ 7 - 184 ÷ 8 = ?

(1520 - 1350) ÷ (550 – 500) = ?

Find the value of ‘x’ if (5 × 196 – 340 ÷ 17) ÷ 20 = √1600 – x.

300% of (3341 – 471) = ? × (√4225/195)

What will come in the place of question mark (?) in the given expression?

(16 × 22 + 23) ÷ 15 + 24 = ?² – 16 × 2

What will come in place of ‘?’ in the given expression : 

? – (22 × 25 + 70% of 160) = 27²

? ^(1/2) = 236 – 25 × 18/2 + 396 ÷ 22

6612 ÷ 19 - ?% of 240 = -2196
