how do I write 2.16 trillion in number form?

Answer 1

2,160,000,000,000

Hope that helps ;-)

Answer 2

1 X 10^3 = 10^3 = thousand = 10 X 10 X 10 = 1,000
10^6 = million
10^9 = billion
10^12 = trillion; thus 2.16 X 10^12 is the numeric equivalent to 2.16 trillion and to 2,160,000,000,000, which most answerers correctly gave.

Note that 10^n indicates n digits follow the number in front of the decimal point. Thus, in 2,160,000,000,000, there are twelve digits (mostly zeros) following the 2 in 2.16. 2.16 thousand, for example, can be written in scientific notation as 2.16 X 10^3. This means that there are three digits after the 2; and those three digits are 1, 6, and 0 as in 2,160.

If you find you are dealing with large numbers, best learn the scientific notation (with the 10^n notation) if you haven't already. The big numbers are much easier to handle in scientific notation.
