Same Sign = Find the Sum

Different Sign = Find the Difference

Since the signs are the same $(- -)$ $(- -)$ , we find the sum

$4 - (- 2)$ $4-(-2)$ $=$ $=$ $4$ $4$ $+$ $+$ $2$ $2$

Next, use the number line and start at $4$ $4$ , then add $2$ $2$ by moving right $2$ $2$ places

$4 + 2$ $4+2$ $=$ $=$

$4 + 2$ $4+2$ $=$ $=$ $6$ $6$

$6$ $6$
