Question

Explain the difference in meaning between each of the following pairs of expressions :

$ab-c$ and $a(b-c)$

Answer 1

For $ab-c$,

$ab$means $a$ multiplied by $b$.

and $-$refers to subtraction or minus .

So, $ab-c$ can be written as $a$ multiplied by $b$minus $c$.

Now for $a(b-c)$,

$(b-c)$ means $b$is diminished by $c$.

and $(b-c)$ is multiplied to $a$.

Hence, $a(b-c)$ can be written as $a$ multiplied by $b$diminished $c$.

Final Answer : Therefore, The difference between the pairs of expressions is that $ab-c$ can be written as $a$ multiplied by $b$minus $c$ and $a(b-c)$ can be written as $a$ multiplied by $b$diminished $c$.
