03: Subtract Integers

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

 $7\ -\ \left(-2\right)\ =\ ?$  

•  $7\ -\ \left(-2\right)\ =\ 9$  

•  $7\ -\ \left(-2\right)\ =\ 5$  

•  $7\ -\ \left(-2\right)\ =\ -5$

Like this...

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

•  $-5\ -\ 3\ =\ 8$  

•  $-5\ -3\ =\ -8$  

•  $-5\ -3\ =\ -2$
