I am interested in combinatorics, probability, dynamical systems, and various other topics.

comment Nice sign-expansions of special surreal numbers
What's the best source of information on how to define addition, multiplication, and division directly on sign-expansions (as opposed to converting sign-expansions into LR-forms and applying Conway's recursive rules)?

I'd like to know more about the elementary argument based on the IVT that Christian Remling refers to. (I see how to proceed if $f$ is piecewise monotone, but does this follow from my hypotheses?)

Eric, like Todd, is 100% right. I've updated the question accordingly.

You're quite right! I wrote "$SL$" unthinkingly. I'll fix the post (leaving tracks so that your comment still makes sense to later readers).
