(SUMMATIVE) Integers Rule - Y7

 $\left(-5\right)-\left(+3\right)=$ 

is the same as: 

• - 5 + 3

•  5 + 3

• - 5 - 3

• - 3 + 5

 $-\left(-10\right)+\left(-10\right)=$  

• zero pair

• - 20

• + 20

• +10

 $14\ -\ 25\ =$  

• - (-14) - (-25) =

• + (+14) - (-25) =
  

• + (-14) - (+25) =

• - (-14) + (-25) =

 $-\left(+1\right)-\left(-1\right)+\left(-1\right)=$  

• +1

• -1

• -3

• Zero pair

 $-\left(+4\right)+\left(-4\right)=$  

• +4

• -4

• -8

• +8

Look at the number line. That represents:

• -(+4) - (-8)

• +(-3) + (+7)

• -(+2) + (+6)

• -(+3) + (-7)

The following drawing represents:

• 5 - 2

Check these tiles. They mean:

• + (+4) - (-6)

• + (+4) + (+6)

• + (+4) + (-6)

• + (-4) - (+6)

Look at these steps. They mean:

• -3 + (-4)

• -3 - (-4)

• -3 - (+4)

• +3 - (-4)

 $5\ -\ \left(-9\right)\ =$  

• 14
