joshua's integer scribe post

How to solve Integers

First Question:
write the question down
5-2= 3

First Step:
write the question in words:
have 5 and owe 2 = have 3

Second Step:
use the tiles to show or help you how to get the answer.
5-2=3
have 5 positive tiles and have 2 owe tiles
   +++++                              --
use zero pair
5 =+++++
2 = - -          
(the highlighted in green means to remove)
 and now it's only gonna have 3 positive tiles which means the answer will be 3.

Second Question:
write down the question
-4-4=8

First Step:
Write the question in words:
owe 4 and owe 4 = owe 8

Second Step:
pretty much straight forward
-4-4=-8
it has both negatives which means you just need to have add the both numbers together and since it's negative (owe) your gonna make the answer negative by just putting a "-".

Third Question:
Write down the question
7-(-9)=16

First Step:
Write the question in words
have 7 remove owe 9 = 16

Second Step:
 Use tiles to show or help to get the answer
7-(-9)=16
have 7 positive tiles and remove 9 negative tiles
use the zero pair, have the negative match to the positive
7= +++++++
-9= - - - - - - - - -  = removed
       +++++++++
after remove all the negatives and leave the positives
then add the whole positive which it will be 16
so the answer to 7=(-9) is 16

Fourth Question:
write the question down
10+4=14

First Step:
write the question in words
have 10 and have 4 = have 14

Second Step:
use the tiles to show or help you how to get the answer.
10+4=14
have 10 positive tiles and have 4 positive tiles
it pretty much straight forward, just add the two number and the will be the answer,
so  the answer to 10 + 4 is 14.

  1. I liked how you explain each and every step to get the answer for a question like this for subtracting and adding integers. To make this better you should add a video about integers and put more pictures to explain how you got the answers. Anyway. Good Job.

  2. I really like how you show the steps in order. I know what you're saying and I understand how to remove integers. However you didn't say ''owe'' or ''have'' on one of your First Step. It was ''have 7 remove owe 9 =16''. 16 can either be a ''have'' or an ''owe'' which can be misleading. Also you need a video about what you taught me. This was excellent and I love the effort you put into it. Keep up the great work!!!

  6. good job! it's easy to understand, simple, and just saying i love the color blue you chose. But back on topic, your explanation was great, sometimes i forget to add steps but this really helps those who are struggling, remember add a video. You did a great job on keeping it short and sweet, but very understandable and detailed at the same time. good job!
