This is because the highest bit represents the largest part of the numerical value, and its value has the greatest influence on the whole numerical value. For example, in the number 432 1, the highest digit is thousands, representing the value of 4000, which occupies the largest proportion in the whole value. Therefore, if the highest digits of two numbers are different, then the number with higher highest digits must be greater than the number with lower highest digits.

If the highest digits of the two numbers are the same, then we will continue to compare the second highest digits, that is, the hundred digits. Similarly, if the second highest level is the same, we will continue to compare the third highest level, and so on. For example, two numbers, 432 1 and 4397, have thousands of 4, so let's compare their hundreds. In this example, one percent of 432 1 is 3, and one percent of 4397 is 9. Since 9 is greater than 3, we can determine that 4397 is greater than 432 1.

In the case of the same number of digits, compare the highest number of digits first.

Matters needing attention in learning mathematical numbers:

1, know the carry rules and operate carefully.

Mathematical digits with different digits have different carry rules. For example, the single digit is 1 in 1 and the decimal digit is 1 in 10. Understanding these laws and applying them to calculation can avoid calculation errors. The calculation of mathematical digits needs to be careful, especially when carrying and borrowing. If there is an error in the calculation process, it may lead to an error in the calculation result of the whole problem.

Practice more: the calculation of mathematical numbers requires a lot of practice. Through a lot of practice, you can master the calculation method skillfully and improve the accuracy and speed of calculation.

2, pay attention to the foundation, pay attention to the unit.

Learning mathematical numbers needs to start with basic knowledge, such as the concept of numbers, the methods of carrying and borrowing, etc. Only by mastering these basic knowledge can we better understand and learn advanced mathematics. When calculating mathematical digits, we should pay attention to the conversion of units, such as 1 hour =60 minutes, 1 minute =60 seconds, etc. If the unit is not converted properly, the calculation result will be wrong.
