Numbers: Everyone's language.
Ancient numbers
In ancient times, people wrote numbers in many different ways.However,they nearly all counted in tens.
Zero
The system of numbers today consists of the numbers from 1 to 9 and 0 (zero).The Indians first invented and developed the 1 to 9 system of numbers. They then invented the zero. This was a very important invention because it made it easier to write big numbers and to calculate.
Calculating machines
One of the first calculating machines was an abacus. Abacuses are fast and accurate,so people still use them today. On the abacus in the picture, the beads on the wires represent ones, tens,hundreds and thousands starting from the bottom wire.
Now,we use modern calculators.The picture on the right shows a modern calculator. It can add,subtract, multiply and divide. It can also calculate percentages and square roots.

计算工具
史上最早的计算工具之一是算盘。算盘及准确又能够很快的使用，所以至今人们也还在使用。可以看到图上的算盘有套在铁丝里的珠子。这从最低下开始分别代表个位数，十位数，百位数和千位数。
现在，我们用计算器。右边的图显示的是一部现代计算器。它分别可以加、减、乘和除。它也可以计算百分比和开方。
