Hi; I can help you with this ... Happy Monday to you.
Let's look at them one at a time. On the first one: Can you tell me what 7 + (-10) is? Can you tell me what -13 + 17 is?
You too, are you good with math
Yep, I'm good with math (I've taught for over 30 years and have a doctorate in math).
1. -3 2. 4
Okay, so on (1), remember that "<" means " to the left of on a number line ". If you mark your -3 and your 4 on a number line, does -3 lie to the left of 4 ? If so, the first one is true. What do you think?
I think that sounds right
So what's your answer .... do you think -3 lies to the left of 4 on a number line? (Yes or no)
Yep! So the first one is true. Good. Now, tell me the values of the left-side and right-side on the second one.
1. 9 2. 11
Perfect. So, the question here is: Is 9 > 11 ">" means "to the right of" on a number line. Plots 9 and 11. Does 9 lie to the RIGHT of 11 on a # line? (Yes or No)
Correct. So, the second one is false. For the third one, remember the "=" means "live at the same place on a number line". Try that one, and tell me what you think the answer is.
Yep, it's false. 6 and -6 definitely don't live at the same place on a # line. The last one is the trickiest of all these. Simplify the left side; simplify the right, and remember what ">" means ... you try it.
By the way, there are memory devices for remembering what ">" and "<" mean here: http://www.onemathematicalcat.org/algebra_book/online_problems/big_small.htm (The memory devices here work with both positive and negative numbers, so they're more versatile than the "alligator" memory devices).
Correct Because -19 is higher than -22
Awesome! Yep, -19 lies to the right of -22! It's true. Good job!
If you want lots more practice like this, you can go here: http://www.onemathematicalcat.org/algebra_book/online_problems/ineqTF.htm Have a great day... bye...
I don't know how to metal or I would
You already did! You click the little medal just to the left of the number on the right side of the screen.
