Question

) Sum of numbers a and b subtracted from their product

Answer 1

Answer:

Sum of a and b = a + b

Product of a and b = a × b

Therefore, sum of numbers a and b substracted from their product =

a × b - a + b

a × (-a) + b + b

-a + 2b

Answer 2

$\textrm{Required Answer = Product of 'a' and 'b' - Sum of 'a' and 'b'}$

$\longrightarrow\textrm{Required Answer = (a \times b) - (a + b) = ab - (a + b) = ab - a - b}$
