Using the numbers [15, 25, 50, 60], create an equation that equals 80 using basic arithmetic operations. Let’s break down your solution into two parts: one for a beginner who might find it tricky, and a more advanced strategy that expert players would consider. Show your work in <think> </think> tags. Also, discuss any discrepancies between the two solutions and suggest why an advanced player might choose the simpler equation when a more complex one would appear to produce a greater result first. Finally, return both equations and the discussion in <answer> </answer> tags, for example: <answer> (15 * 5) + 25 + 50 + 60 = 80 </answer>.<|im_end|>
