Steps of adding -6 + 4 using number line are as following:
1) Draw a number line by ranging from -10 to +10.
2) Point out -6 on the number line.
3) Because 4 is added to -6 on the number line, please move 4 number right to -6 on the number line. We always go right in addition and go left in subtraction on the number line.
4) The number we reach 4 on right side would be our final sum.
5) From the number we can clearly see that moving 4 number on right to -6, we get -2.
So, final answer is -2.
