The calculation method is as follows:

10 million (10 million * 10 = 10 million; 1000,0000* 10= 1,0000,0000);

1 0 billion (1100 million * 100 =1100 million; 100,0000* 100= 1,0000,0000)。

Extended data:

When calculating with decimal system, we should abide by the two principles of decimal system based on decimal system and decimal system based on decimal system, that is, all numbers are represented by 10 basic symbols, and the basic symbols are filled with decimals. At the same time, the same symbol represents different values in different positions, so the position of the symbol is very important.

The basic symbols are ten numbers from 0 to 9. To express 10 times of these ten numbers, move these numbers one place to the left, and fill in 0 in the space, that is, 10, 20, 30, ..., 90; To represent 10 times of these ten numbers, continue to move the position of the number to the left, that is,100,200,300, ...

To represent a number110, move the position of this number to the right, and fill the space with 0 if necessary:110 bit 0. 1,100 is 0. —— Excerpted from Statistics Appendix 3 "Basic Mathematics" P205-6[ English] Tim Von Hanneken 2008.338+0
