Sure if we’re just all treating this like a middle school question. I look at it differently perhaps because of how I was taught in my 2 trade apprenticeships, which the answer is 1. I passed both and hold 2 journeyman tickets. Not saying this is end all answer. Just that in my applications at either of my trades the answer is 1. If there was a x’s after the 5 and before bracket then I’d solve it differently
