Ten thousand digits include ten thousand digits, one hundred thousand digits, one million digits and ten million digits. Billions include billions, billions, billions and billions of digits. Numbers refer to the position of each number in a number. The number of digits in the integer part starts from the right, and every four digits are one level. Each level includes one digit, ten digits, hundred digits and thousand digits, indicating how many ones there are.
Tens of thousands include tens of thousands, hundreds of thousands, millions and tens of millions, indicating how many tens of thousands there are; Billion includes one billion, one billion, one billion, one billion, which means how many billions. The decimal places are decimal, percentile and thousandth from left to right.
A few tenths, a few percent, a few thousandths. The number of digits of a natural number is called the number of digits. For example, the number 9 contains only one number, so 9 is a number; Five digits 12345 contains five digits: one, ten, hundred, thousand and ten thousand.
Numbers mean that when writing numbers, the numbers are arranged side by side in a line, and each number occupies a position. These positions are called numbers. Starting from the right end, the first place is the unit, the second place is the tenth place, the third place is the hundred places, the fourth place is the thousand places, and the fifth place is the ten thousand places, and so on. This shows that the concept of counting unit and number is different.
