• you combine like terms on 2-step algebraic equations to simplify it.
• a positive integer and a positive integer is a like term
• a negative integer and a negative integer is a like term
• 2w and 4w is also a like term
• For Example,  
  

As you see what I did there, I combined the two like terms to simplify the equation to make a 1-step algebraic equation. if the variable comes last then I will show you how to simplify it combining the like terms

This is my first post about Integers. I will be talking about Adding and Subtracting.

• When adding and subtracting integers you can use many ways to get the answer like using the number line and absolute value.
• The most used way to show integers are integer chips.
• When you use integer chips you take the question and draw circles, shaded or non-shaded to show negative and positive. Then you circle out the zero pairs.
• Zero pairs are a positive and a negative combined.
• Absolute Value is when you keep the symbol(+ and -)of the larger number than the other number and it would give you an idea of what the would be.

In class we made a movie about adding and subtracting integers. Here is my movie

• If you have a negative or a positive you have a zero pair.
• If you have a negative and a negative you need to add them because you need a negative and a positive  to make a zero pair.
• If you have a positive and a positive you need to add them because you need a positive and negative to make a zero pair.
• You can do it with a number line or positive circles and negative circles.
• You can use words too.
• If you can not remove an integer number you have to make it a zero pair so you can get the right answer.
• If there is a plus sign it an and, and if there is an subtract sight its remove
• You can say (ex: 3+(-2)=+1 have 3 and owe 2 or 3 and -2).
• If you need help to find which one is negative or a positive you can just put a + and it represents a positive and a negative.
• If a positive and a negative combined it does not make anything so that's why it's called zero pairs and you need to circle them too.

• positive and a positive will give you a negative
• negat

• The absolute value of  x is x ( [-18] = 18
• The amount of space on a number line is its absolute value
• When both signs are positive then the answer will be positive
• When both signs are negative, the answer will be negative
• Always circle your zero pairs or what you are taking away

This is what i know about Adding and Subtracting Integers

• When adding or subtracting integers u always have to circle the zero pairs if their are zero pairs.
• 
  
• When adding negative it turns into a 
  

This is my first post about integers. I will be talking about adding and subtracting.



This is what I know about adding and subtracting integers:

• a zero pair is both positive(s) and negative(s)
• when adding a negative and positive, you look for the largest absolute value to see if the answer is negative or positive
• you can use a number line or integer chips to solve the questions
• subtracting negatives, you just add more negative chips since you're just removing, and remove what needs to be removed
• number line; put a starting dot to where you start, make an arrow to the answer, write the question on the arrow, then circle the sum
• -37 + -41 = owe 37 and owe 41= owe 78
• integers scripts: +3 + -2 = +1 [you put 3 positives on your paper. You put two negatives on your paper. Then find your zero pair and circle them. You are left with one positive.]
• absolute value: holds the value of what it is we are talking about.
• 3-7= -4 [ 3 REMOVE 7]
• -9 + +7 = -2 [-9 AND/COMBINE +7]

This is what i know about adding and subtraction integers.

• If there are odd number of negatives it is always negative.
• If there are even number of positives it is always positive.

This is my first post about integers. I will be talking about adding and subtracting.

• An Absolute Value is when you keep the sign - or + of the absolute larger value.
• To remove something that is not there you have to use a zero pair.
• When a question has 4 positives and 3 negatives and is asking you to take away three negatives from your positives.

This is my first post about Integers. I will be talking about Adding and Subtracting.

This is what I know about adding and subtracting integers:

• When you can't remove what is not there you have to add a zero pair
• Circle to dedicate zero pairs or removing 
•  Finding the absolute value of an integer can help you find the right sign to use

• When adding or subtracting integers, to make it easier for me is to make the adding or subtracting sign opposite and do the same with the second integer. Make it opposite.

• You can also make adding and subtracting integers by modeling. It makes it a lot easier.

This is my first post about Integers. I will be talking about Adding and Subtracting Integers.

• When adding or subtracting integers u always have to make zero pairs so it will make the question a lot easier 

E.g. 4+(-2)= +2

This is my first post about Integers. I will be talking about Adding and Subtracting.

• Adding negative integer to another negative integer are like adding positive integer to another positive integer but using negative integers.

• Adding positive integer to a negative integer are like subtracting a positive integer to another positive integer but using addition symbol than a subtraction symbol.
• Subtracting a positive integer to a negative integer are like adding a positive integer to another positive integer but using a subtraction symbol than a addition symbol.
• Subtracting a negative to another negative integer are like subtracting a positive integer to a positive integer but using negative integers.
