1016到2021之间有多少个整数？
数字系统是一种借助不同集合中的标准规则和符号位来表示数字的方法。数制以数字或文字的形式表示数轴的数字。十进制数系统、二进制数系统、八进制数系统和十六进制数系统是用于表达数学图形的一些通用数系统。
数字
数字是参与数学运算（如加法、减法、乘法和除法）的数值。数字用于营销、销售、贸易、天气预报、媒体管理和许多其他学科的基本部门的日常生活中。它们是测量、计算、标记等的标准。
根据包含在一个组中的数字，这些数学图形分为不同的类型。
- 实数
- 复数
- 自然数
- 完整的号码
- 素数
- 有理数
- 无理数等
整数
整数是包括所有计数数字以及零的数字集合。整数集不接受负整数、分数和小数值。整数的集合从 0、1、2、3、4、5、6 等开始计数。也可以说所有的自然数和包括的0都是整数。因此，所有自然数都是整数，反之则不然。
1016到2021之间有多少个整数？
解决方案：
The number of whole numbers presents between two consecutive numbers A and B can be determined by the method.
B – A – 1
In which B stands for the larger number and A stands for the smaller number. And, 1 is subtracted at the last to exclude one of the endpoints as the question asks about the whole numbers “between” two consecutive numbers. According to the question, there are two consecutive numbers 1016 and 2021 and the number of whole numbers between them can be determined by B – A – 1
where,
A = 1016
B = 2021
Now,
= 2021-1016
= 1005
Then,
1005 – 1
1004
Therefore, there are 1004 whole numbers between 1016 and 2021.
示例问题
问题1：1042和1210之间有多少个整数？
回答：
There are 167 whole numbers between 1042 and 1210.
As by the method B – A – 1
1210 – 1042
168
Then,
= 168 – 1
= 167
问题2：1018和1203之间有多少个整数？
回答：
There are 184 whole numbers between 1018 and 1203.
As by the method B – A – 1
= 1203 – 1018
= 185
Then,
= 185 – 1
= 184
问题 3：51 到 71 之间有多少个整数？
回答：
There are 19 whole numbers between 51 and 71.
As by the method B – A – 1
= 71 – 51
= 20
Then,
= 20 – 1
= 19
问题4：10到100之间有多少个整数？
回答：
There are 89 whole numbers between 10 and 100.
As by the method B – A – 1
= 100 – 10
= 90
Then,
= 90 – 1
= 89
问题 5：1019 和 1200 之间有多少个整数？
回答：
There are 180 whole numbers between 1019 and 1200.
As by the method B – A – 1
= 1200 – 1019
= 181
Then,
= 181 – 1
= 180
