Question

Find the value of $3+6$ using a number line.

• A. $7$
• B. $8$
• C. $9$
• D. None of the above

Answer 1

The correct option is C $9$

$\underset{–}{\text{Need to find:}}(3+6)$ using a number line

$\underset{–}{\text{Step - 1:}}$ Start at zero and move $3$ units to the right of it to arrive at $3$ as depicted in the below figure.



$\underset{–}{\text{Step - 2:}}$ The second number is $6$ that is positive. So, move $6$ units to the right of $3$, and we arrive at $9$ as illustrated below.


Therefore, $3+6=9.$

$\therefore$ (c.) is the correct option.
