Lesson 4: Comparing negative numbers

Numerical inequality word problems

In this math lesson, we learn to compare quantities using inequalities. John makes pasta dough with two types of flour, finding that wheat flour (3/2 cups) is greater than regular flour (3/4 cups). We also compare ocean depths, discovering the Diamantina trench is deeper than the Bering Strait. Lastly, John makes noodles, comparing tapioca flour (11/16 cups) and rice flour (3/8 cups).

• Hi People, how ya doin? How's quarantine?
• Over and done
• Does inequality mean < or > or = or can it be something else too?
• "Inequality" is the opposite of equality, meaning they are not equal. > (greater than), < (less than) ≠ (not equal to) are all strict inequalities as they are not equal to each other. There are some inequalities that are a little more flexible, where it could be equal to, such as ≥ (greater than or equal to) and ≤ (less than or equal to).
• how do you whatch the video
• You click on the blue play button or arrow. Next, you point your eyes towards the screen. Finally, you watch the entire video.

Hope you learned something.

• First, Thanks for all your help, KA!
This video actually doesn't match the exercise titled "Inequality word problems." This video is comparing two numbers instead of writing an inequality with one variable. On the other hand, the video titled "Inequality word problem: one variable" actually only shows 2 variable examples which is confusing. It would be helpful to have videos that match the assignments (as almost all of them do...so this is a fluke.)
Thanks for everything...Michele
• find the slope of the equation below

y-2=4/5(x+8)
• The answer is this:(y=4/5(x+8)+2). This is because you have to put the -2 (which is next to the y)in the end of the problem to find the value of y.

• A vertical number line is labeled with integers from negative 6 to 2 from bottom to top. There are two points on the number line. The point 1.2 is located above 0, between 1 and 2. The point negative 4.4 is located below 0, between negative 4 and negative 5.
• Hello there I'm an 8th grader i want to be a math tutor so i thought i should start here on khan anybody need help just ask?
• how do we know when to use <
• You use this when the number on the left is smaller than the right. Sort of like if I had this:
18___25
You would put that symbol in, because 18 is smaller than 25.
