At about the 0:55 mark, the teacher says 4-1.6 is going to give me 3.4; he should have said 2.4.
In this lesson, you will learn how to find the length of a line segment given the whole and part of it. By subtracting the known part from the known whole, you can determine the missing length of the segment. This method involves using basic arithmetic and is a useful skill for many real-world applications, such as measuring distances or calculating dimensions in construction.
Finding the length of a segment given the whole and part
I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
Questions answered by this video:
