Morphology
The phrase denotes a theorem (a provable statement) concerning a binomial (an expression with two terms), so its meaning is directly compositional from the constituents. Although technical, the relation is transparent and cross-linguistically analogous, so a learner who knows 'binomial' and 'theorem' would readily understand it.
Etymology
Binomial theorem gets its name from binomial, meaning an expression with 'two parts' like a + b, and theorem, meaning a 'rule'. Think of it as a simple recipe that shows how to change a + b when you raise it to a power, so it tells you how to 'expand' that expression into many terms.
