In a mathematical exercise, students are tasked with matching the appropriate strategy to simplify a set of given problems. The problems provided are: 73 + 55 = 120 + 8 = 128, 74 - 36 = 7 + 9 + 8 + 5 + 2 + 1 + 3 = 30 + 5 = 35, 44 - 6 = 40 - 2 = 38, and 24 + 4 = 28. The available strategies to choose from include taking away an extra ten then adding back ones, composing addends into tens and ones, taking away tens then taking away ones, and decomposing addends into tens and ones. The goal is to correctly assign a strategy to each problem based on the steps shown. Place the description of the strategy used to simplify the problem below the problem.
