Jun 7, 2024 · As another example, it's much easier to remember that a trillion is written with four sets of three zeros than it is to count out 12 separate zeroes. While you might think that that one is pretty simple, just wait until you have to count 27 zeros for an octillion or 303 zeros for a centillion.

Large numbers are numbers above one million that are usually represented either with the use of an exponent such as 109 or by terms such as billion or thousand millions that frequently differ from system to system.

The Chicago Manual of Style recommends spelling out the numbers zero through one hundred and using figures thereafter—except for whole numbers used in combination with hundred, thousand, hundred thousand, million, billion, and beyond (e.g., two hundred; twenty-eight thousand; three hundred thousand; one million).
Feb 15, 2020 · Write numbers with commas separating sets of three zeros so that it’s easier to read and understand the value. For example, write one million as 1,000,000 rather than 1000000. The set of three starts as you move to the left of a decimal point (the last zero).
Aug 11, 2014 · Powers of Ten – Metric Prefixes. Prefixes for the powers of ten are grouped into sets of three zeros, with smaller increments near the number 1. Scientific notation is a useful means to write out very large or very small numbers using powers of ten and exponents.
Both scientific notation and standard form refer to numbers written as a number between 1 and 10 multiplied by 10 to the power of some other positive or negative number. For example consider the following lists: 10 1 = 10. 10 2 = 100. 10 3 = 1000. 10 4 = 10000.
