Example: \( 44+55=55+44= \) a. \( 51+(19+46)= \)

Did you know that the order of addition doesn’t change the sum? This property is called the commutative property, which applies to addition (and multiplication) and makes math way more flexible! So in your example, no matter how you group the numbers, the total remains the same. For your specific example, you can group it as \( 51 + 65 \) (since \( 19 + 46 = 65 \)) which equals \( 116 \). So, whether you add \( 51 + (19 + 46) \) or directly \( 51 + 65 \), you're still getting \( 116 \) at the end! Keep those math tricks in mind—they can save you time and headaches!
