How do I find 85 using parenthesis with the equation 2+3*16+1?

Question

tkhunny · Answer

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.

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?

anonymous · Answer

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

mathmate · Answer

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)
