Question
What is the midpoint of the line segment described by (1,4) and (3,7)? I don't know how they got the correct answer, (2, 5.5). Please help. thanks

Answer
Hello Emi,

To find the midpoint of a line segment, what you do is find the midpoint of the x coordinates and the y coordinates. So the x coordinate of the midpoint is (1 + 3)/2 = 2. The midpoint of the y coordinates is (4 + 7)/2 which = 5.5. So it is (2,5.5).



I hope this helped,

Please feel free to ask if anything wasn't clear,

Expertise

I can answer a variety of questions on mathematics. Questions on trigonometry, calculus(preferably single variable), algebra, geometry, and number theory will be answered. I cannot answer questions on abstract branches of mathematics such as group theory. I also cannot answer questions on statistics. In number theory, I can answer questions on congruences, prime numbers, units, functions, and the riemann-zeta function.

Experience

I have studied advanced math my entire life. I started calculus in sixth grade. I have attended numerous math competitions and I am attending math organizations such as the San-Diego math circle. Also, this year I have been invited to the USAMO which is a prestigious math competition (Every year the USAMO invites 500 students from across the USA to participate in this competition. The top 6 go to represent the USA in the International Math Olympiad).

Organizations
I am in the San Diego Math Circle

Education/Credentials
I am entering high school and have received a perfect score and the STAR test 5 times in a row. I also have gotten recognitions in the AMC 10, AIME, Math Counts, and ARML. Additionally, I have won the San Diego Math Olimpiad twice in a row.
