Determine the answer to 3 + -5 and explain the steps using a number line

Adding a positive to a negative, you would look at the number with the greater absolute value, and that number would determine the sign of the sum. 

5 - 3 = 2

Since 5 is bigger, you use that sign

-5 

-2

-2

-5 -4 -3 -2 -1 0 1 2 3 4 5 

That is the number line. Add 3 to -5 and you get -2. ( a negative + a positive = A negative) ( A negative + a Negative = A positive) 

Hope that helps :)
