Let’s spice it up: how should we handle multiple sets of inputs? Let’s say we want to run operation F on both (a, b, c) and (x, y, z). We know to multiply the first input by the first value, the second input by the second value, the third input by the third value, and add the results. We could abbreviate the entire function as (3, 4, 5). Next, how should we track our operations? Remember, we only have “mini arithmetic”: multiplications by a constant, with a final addition. We could write it (x, y, z) too - hang onto that thought. First, how should we track a bunch of inputs? How about a list: x
