Answer
a. There exists a real number u such that for all real numbers v, uv=v.
There is a real number whose product with another real number is always equal to the other real number.
b. negation: $\forall$ real numbers u, $\exists$ a real number v, such that uv $\neq$ v.
For all real numbers u, there is a real number v, such that uv $\neq$ v.
