What is the difference between the sum of the first 100 positive even numbers and the sum of the first 100 positive odd numbers ?
The first 100 positive even numbers are 2; 4; 6;...; 200. Their sum is \(\dfrac{\left(200+2\right).100}{2}=10100\).
The first 100 positive odd numbers are 1; 3; 5;...; 199. Their sum is \(\dfrac{\left(199+1\right).100}{2}=10000\)

The first semester begins in September and ends before the Lunar New Year, while the second one begins right after the first one and lasts until June the first. Children in Vietnam go to school six days a week from Monday to Saturday and a typical school day runs from 7:00 to about 11:30 in the morning. Vietnamese students are expected to take school very seriously and to work hard. Most periods begin with a small test. The teacher calls on some students to stand and answer a few questions to check their understanding of the last lesson.
After school, Vietnamese students take part in a lot of activities. Some students play sports. Soccer, table tennis, and badminton are the most popular. Others enjoy going swimming. A few students like music and movies. They often practice playing musical instruments in the music hall or go to the cinema with their friends to see the latest films.
