**This part of the post will show you how I understand how to subtract integers with brackets.**

**Step One**: You write out the question: 7-(-9) =

**Step Two**: You have to rewrite it using words such as owe, have, remove, & and.

Note: Owe means it's a negative number and have means it's a positive number.

Answer: have 7 remove owe 9

Step Three: You model it in integer tiles to help show that you understand or to help you get the answer.

7- (-9) = + + + + + + + - - - - - - - - -

After that, you have to make zero pairs so first you match the negatives (owes) with positives.

7- (-9)= + + + + + + + - - - - - - - - -

+ + + + + + + + + (pretend they're the same size)

Then, you removes those owes/negatives and you add what's left (positives) to your first amount of positives which is 7.

7- (-9)= + + + + + + + - - - - - - - - -

+ + + + + + + + + (The highlighted part means that it is leaving.)

After that, you now add it together so : + + + + + + + + + + + + + + + + = 16 positives or just 16.

Lastly, you add in your answers to the question.

7- (-9) = 16

have 7 remove owe 9 = have 16

Now, you'll see how I did the other questions.

Great scribe post, I was a bit confused with the concept but this helped me big time. You did it just right, you added detail but you didn't write a book unlike some people (We all know who this is)... Anyways, thanks for the post I really appreciated it!

ReplyDeleteGreat job on your scribe post. i really understood what you're explaining and your pictures help because there are verities in questions. also remember to add a video and a link to a integer game of some sort. great job!
