Question

Which of the following images represents 9 - (-5)?

• A.
• B.
• C.
• D. None of the above

Answer 1

The correct option is B

9 - (-5) $\Rightarrow$ Subtract -5 from 9, i.e., take away -5 from 9.

$\underset{–}{\text{Step 1:}}$
9 represents 9 positive chips.
$\underset{–}{\text{Step 2:}}$
As one negative chip and one positive chip cancel each other, we can include a total of 5 negative and 5 positve chips to the above mentioned 9 positive chips without changing its resultant value.

$\underset{–}{\text{Step 3:}}$
5 negative chips represent -5.
Now, -5 has to be subtracted from the 9, so, removing 5 negative chips will result in 14 positive chips.
$\therefore$ Option b is the correct one.
