Recognize an equivalent structural rewrite

Problem

Rewrite \(46~+~19~+~54\) by changing the order of the addends to show the commutative property. Arrange the addends so that \(46\) and \(54\) are next to each other. Do not find the final sum.

Side-by-side comparison for reordering 46 + 19 + 54 using the commutative property so that 46 and 54 are next to each other. The left panel shows the original expression and a note about making 46 and 54 adjacent. The right side shows four options: A. 46 + 54 + 19, B. 54 + 19 + 46, C. 46 + (19 + 54), and D. 46 + 19 + 54.
