A guinea was an old unit of British currency worth 21 shillings (£1 1s). Translated to modern currency it would be £1.05, but exchange rates have changed radically over the decades. Without knowing when the item in your question was priced it's not possible to translate to USD.
Under the current "short scale" of numeration, a "trillion" is one thousand billion or 1012. (The superceded "long scale" used names that increased by a factor of one million, making the old billion 1012 and the old trillion 1018.) So a trillion = one thousand billion or one million million
In the US "short scale" a billion is one thousand million. (1000 x 1,000,000 or 1 x 109).Larger named numbers also increase by thousands.In the long scale used in some parts of Europe, a billion is a million million.(1,000,000 x 1,000,000 or 1 x 1012)Other larger numbers increase by millions, rather than thousands.(1 trillion = 1 million billion)
$1012
1.353 x 1012 Or 1,353,000,000,000
1012
Something that is a trillion starts off with this base 1012. Therefore, 3.65 trillion is 3.65 x 1012 in scientific notation.
percent of 1012 = 101200%= 1012 * 100%= 101200%
Just picked one up for $2100.
1 trillion = 1012 1000 = 103 Then subtract exponents.
Whatever someone is willing to pay.
You could write it in full as $5,839,000,000,000. You might wish to write it in scientific notation as $5.839 * 1012.
1012 pennies is £10.12. If you meant 1012 this is 1010 or 10,000,000,000 pounds
1012 + 13334333574 = 13334334586
