978, of which 360 are 6-digit numbers.If you may use each of the six digits only once, then you can only have 3 pairs of 2-digit numbers beginning with an odd digit.e.g.12 and 34 and 56or 14 and 36 and 52or 16 and 32 and 54
-- If the place to the right of the place named contains a digit larger than 4, then add ' 1 ' to the digit in the place named. If not, then don't. -- Discard all digits to the right of the place named.
Remember , when starting from the decimal point, and moving to the left, each digit column is named ;- Units, Tens, Hundreds, Thousands, Tens of thousands, 'Hundreds of thousands' and ' millions. Again starting the with decimal point, and moving to the right, each digit colum is named ; 'Tenths,' , Hundredths, 'Thousandths', Ten of Thousandths', Hun dreds of thousandths, & millionths. Note the use of '-ths' in the decimal digits. As an example 1234.567. '1' is thousands '2' is hundreds '3' is tens '4' is units '5' is tenths '6' is hundredths '7' is thousandths. Such a numbers as 1,000,000 is said as 'one million; Conversely such as number as 0.000001 is said as 'one millionth'.
Armstrong numbers are properly termed pluperfect digital invariant (PPDI) numbers. For an n-digit PPDI, the number is equal to the sum of each of its digits raised to the nth power. For example, for n = 3, there is 153 = 1^3 + 5^3 + 3^3 = 1 + 125 + 27. Incidentally, the mathematician G H Hardy stated that there are only four 3-digit PPDIs. He added that, although amusing, "there is nothing in them which appeals to the mathematician".Armstrong numbers are apparently named after a computing lecturer at the University of Rochester named Michael F Armstrong. In the mid 1960s he devised Armstrong numbers as an exercise for his students.
He didn't. Someone else, named Michael Keith, re-worked the Edgar Allen Poe poem The Raven, so that the sense of the original was retained, and the number of letters in the successive words (including the title) matched the successive digits of pi.

Question One. 6 x 5 x 4 x 3 x 2 x 1 = 720. Question Two. 3 x 5 x 4 x 3 x 2 x 1 = 360

A 12-digit number is called a trillion. In the International System of Numeration, each group of three digits is named based on powers of a thousand. Therefore, a 12-digit number would represent a quantity in the trillions.
