Minus a minus turns into a plus.  Most important thing to remember.  

 

So -1 -(-5) is the same as -1+5.  And that is the same thing as 5-1.  

 

Your answer is 5-1 = 4.

 

 

Remember that "minus a negative" turns into "plus a positive".  So any time you see two negative signs next to each other, turn them both to positive.  Thus you get (-1)+(5)=4

when you subtract a number by a negative you are actually adding the number so (-1)-(-5) is the same as  -1+5 which equals 4.
