Question

Sum of numbers $a$ and $b$ subtracted from their product. Form an algebraic expression.

• A. $a+b-ab$
• B. $ab-(a+b)$

Answer 1

The correct option is B $ab-(a+b)$

$\underset{–}{Step1:}$
First, we need to add the two numbers $a$ and $b$. This can be done as:
$a+b$

$\underset{–}{Step2:}$
Now, we need to find the product of $a$ and $b$. This can be done as:
$a\times b=ab$

$\underset{–}{Step3:}$
Now, we need to subtract the sum of $a$ and $b$, i.e., $a+b$ from their product $ab$. This can be done as:
$ab-(a+b)$

Therefore, option (b.) is the correct answer.
