    There are only a few possibilities. Try some. 2+3*16+1 = 2 + 48 + 1 = 51 -- Nope 2+(3*16)+1 = 2 + 48 + 1 = 51 -- Whoops! Same thing. 2+3*(16+1) = 2 + 3*17 = 2 + 51 = 53 -- Nope. Try other things.

    (2+3)*16+1=85

    (2+3)*16+1=5*17+=85

    Maybe you can help me with this: (w^2-w+1)+(w^3-2w^2+99).

    Also must the sum of 3 polynomials again be a polynomial?

    \[\left( 2+3 \right)*\left( 16+1 \right)=5*17=85\]

    The sum, difference and product of two or more polynomials is always a polynomial. The quotient (division) of two polynomials is a rational function (which \(could\) be a polynomial)
