the program must be solved using cycles. starts with (1/2).

Here's a cycle you can use to do your homework

Seriously?

If it's your homework assignment, yes.

If it isn't, what have you tried so far?

you're supposed to recreate a paper with fake math problems? well, why don't you just scan it? maybe we can use html and svg to recreate the paper. You'll have to draw the svg arrows yourself, i have no time for that or the squiggly scribble.

    div.textForm { display: inline-block; position: absolute; top: 3em; left: 16em; width: 8em; height: auto; }
    .invisibleInput { margin: 2px; width: 6em; height: 1.2em; border: solid 4px #000000; border-radius: 30%; }
    .htmlform { display: inline-block; text-indent: 1em; }
    .submit { display: inline-block; position: absolute; left: 2em; width: 3.5em; padding: 4px; border: solid 4px #000000; }

and, honestly, this is the worst code that i could think of. I hope that you fail 🙂 cheating gets you nowehere, unless you're bodybuilding. The Arnold cheat is quite good. I gained 2 inches using the Arnold cheat.

I gained four inches just by giving up rugby, squash and badminton.
