Alright, let's look at this step by step. first off, that y at the beginning just says "okay, we're gonna be dealing or talking about y right now". then, there's some statements. first off, we see "is an integer". that means exactly what it says--y is an integers. that means negative and positive numbers and zero. okay!
now we see 0 <y>=3. this means you is greater than zero, and y is greater than or equal to three. okay--as I write that I see a problem. are you sure you wrote that portion correctly? with that, we won't have a definite set of numbers. let me know if any changes should be made.
