This picture above says "have 84 and have 66", the number line says <- -84 + +66 -> it will equial to -18.



This picture above says "have 76 and have 55 (under (+76) and (+55).)" , the diagram shows a number of me adding 76 and 55 to make 129.

This picture above says " owe 93 and owe 87 (above 93, + and above -87).) the diagram show a crayon as the number line it show me owing a certain item or object  it says "lossing -93 then lossing -87".

- When subtracting something that isn't there, you have to use a zero pair.

Riah's Subtracting Integers Scribe Post Range (-99)-(+99) Worksheet (D)

 If you have a larger number you might want to put the integers on a number line instead of tiles. In order to be able to show removing integers on a number line you need to change the integer behind the negative sign into the opposite so for example (-95) - (+15) = (-95) + (-15)= (-110)

(-37) - (-13)

standard form 

-37 - (-13)

(-30) - (-10)

standard form

-30 - (-10)

(+24) - (-83)

standard form

+24 - (-83)

(-7) - (+75)

standard form

-7 - 75

(-35) - (+98)

standard form

-35 - 98

Integer Subtraction; Worksheet C
3 questions from the first column 

(+1)-(-2)=

positive 1 remove negative 2

Standard Form
+1--2
+1-(-2)

"To subtract something that isn't there you have to use a zero pair"

Since you are removing negative 2 from positive 1 you have to use a zero pair for 2 because you can't take away what's not there. Once you remove the negative 2 your answer is what you have left, which is positive 3.







(+1)-(-6)=

positive 1 remove negative 6

Standard From
+1--6
+1-(-6)

"To subtract something that isn't there you have to use a zero pair"

Since you are removing negative 6 from positive 1 you have to use a zero pair for 6 because you can't take away what's not there. Once you remove the negative 6 your answer is what you have left, which is positive 7.






(-3)-(+4)=

negative 3 remove positive 4

Standard From
-3-+4
-3-4

"To subtract something that isn't there you have to use a zero pair"

Since you are removing positive 4 from negative 3 you have to use a zero pair for 4 because you can't take away what's not there. Once you remove the positive 4 your answer is what you have left, which is negative 7.
