Question 3 - Page 245 Starting from different floors, find the movements required to reach Floor –5. For example, if I start at Floor +2, I must press –7 to reach Floor –5. The expression is (+2) + (–7) = –5. Find more such starting positions and the movements needed to reach Floor –5 and write the expressions.The goal here is to find different starting points and the movements needed to get to the Target Floor of -5. The relationship is Starting Floor + Movement = Target Floor. Here are a few examples: Starting from Floor +1: To get from +1 to -5, you need to go down 6 floors. Expression: (+1) + (−6) = −5 Starting from Floor 0 (Welcome Hall): To get from 0 to -5, you need to go down 5 floors. Expression: 0 + (−5) = −5 Starting from Floor -2 (Video Games): To get from -2 to -5, you need to go down 3 more floors. Expression: (−2) + (−3) = −5
