if were only allowed to use >>, -, + to make a number X times the constant K lets assume K is 17 and K is 20 how to make an expression for each
I was trying to think of ways to do this but I cant.

If $a$ is expressed in binary $2^n\cdot a=a<
$17\cdot a=(2^4+1)\cdot a=(a<<4)+a$ and $20\cdot a=(2^4+2^2)\cdot a=(a<<4)+(a<<2)$
