SUBTRACTING INTEGERS

HOW I GOT THE ANSWERS

Example:

If you still don't get it then watch this video.

Today at math, we were working on Intergers, solving them with number lines.

• Question #1)

(-29) - (-74) =
- To solve this, you re-write (-29) but change the subtract sign, to + and change (-74) to (+74)
- If you come up on a question that's 2nd integer, is a positive, change it into a negitive:
Example: (+45) - (+10) = (+45) + (-10) = +35

Your question should now look like this:  (-29) - (-74) = (-29) + (+74)  = +45
Also! The blue boxes are Zero Pair's.

• Question #2)

(-61) - (-29) = (-61) + (+29) = -32

• Question #3)

(-58) - (-33) = (-58) + (+33) = -25

And if you're still having some trouble with Integers, solving with a number line, here's a

Question #1
(-7) - (-74) = (-7) + (+74)

Standard Form: -7 +74= 

Negative 7 remove negative 74 


Negative 7 and positive 74

                   











                      
                        Have   Owe
Question #2 (+90) - (-24) = (+90) + (+24) 

Standard form: 90 + 24 

Positive 90 remove negative 24

Positive 90 and positive 24 

                   




                                                                                                                                                                              

                   









                   Have    Owe
Question #3 (+23) - (-38) = (+23) + (+38) 

Standard form 23 + 38= 

Positive 23 remove negative 38 

Positive 23 and positive 38
