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

Here's a video that can help you understand more about integer subtraction
