Subtracting Integers on a Number Line

True or false???

5 + (-4) = ?

5 + (-4) = ?

1 positive is left over after the negatives and positives cancel each other
out

Number line

Or, adding groups of negative numbers, so -1 + (-3) = -4

-4 + 7 = ???

-4 + 7 = ???

Either method lands at +3

Multiple Choice

You never subtract integers... But you just "add the opposite!"
Like this...

$$\ 4\ -\ \left(-3\right)\ =\ ?$$  

• $$4\ -\ \left(-3\right)\ =\ 7$$  

• $$4\ -\ \left(-3\right)\ =\ -1$$  

• $$4\ -\ \left(-3\right)\ =\ -7$$  

Multiple Choice

Like this...

$$To\ solve\ -5-\ 3\ we\ add\ -5\ +\left(-3\right)\ and\ \ get-8\ \left(Same\ Signs\right)$$  

• $$-5\ -\ 3\ =\ 8$$  

• $$-5\ -3\ =\ -8$$  

• $$-5\ -3\ =\ -2$$  

Multiple Choice

$$7\ -\ \left(-1\right)\ =\ ?$$  

• 6

• 8

• -6

• -8

Multiple Choice

(-58) - (-5) =

• +63
• -53
