This year’s Nobel Prize in Physics has been awarded to three physicists for their research into attosecond pulses of light. Attosecond: An attosecond is an astonishingly short unit of time, equivalent to one quintillionth of a second (1×10−18 of a second) or one-billionth of a nanosecond. The fundamental significance of attoseconds in physics lies in their ability to shed light on phenomena that were previously hidden from our view
2387.56 + ? – 2248.14 = 1765.45 – 1574.23
3.55% of 8120 – 66.66% of 540 = ? – 28% of 5500
√1567.763`xx` √4400 ÷ 326.9827 + 1223.293 = ?
24.912% of ? – 35.06% of 199.91 = 19.97% of 224.89
- √143.88 X 31.87 + √323.99 X 15.99 - 31.99 X √195 = ?
A number is first increased by 35% and then decreased by 35%. If the net change in the number is 302.5, then find the original number.
(15.15 ×  34.98) + 24.15% of 749.99 = ? + 124.34
124.88% of 60.101 + 18.09% of 849.87 – 22.12% of 1049.93= ? – 19.93
15.15% of (150.50 + 249.50) + 8.08³ - (10.10 of 5.05) = ? of (75.75 - 25.25)
1 ÷ 6.43 of 191.90+75.03% of 220=?²-202.9
