Question

Find the value of $(2+4)$ using chip model.

• A. $2$
• B. $6$
• C. $8$
• D. None of the above

Answer 1

The correct option is B $6$

Suppose, one green chip is equivalent to $+1.$


Now, to find the value of $(2+4)$, we have to add $2$ and $4$ which is equivalent of adding $2$ and $4$ green chips (as one green chip is equivalent to $+1$).

Addition of $2$ and $4$ green chips results in $6$ green chips as depicted in the following.


And, $6$ green chips are equivalent to $+1+1+1+1+1+1=+6=6$.


Therefore, $\underset{–}{2+4=6}.$

$\therefore$ Option (b.) is the correct one.
