Extra Insights

To simplify the expression \( 25 + 20 - 2 - (-18) \), we first rewrite it as \( 25 + 20 - 2 + 18 \). This is because subtracting a negative number is the same as adding its positive counterpart. Now let's evaluate the options to find equivalent expressions. A \( 25 + 20 + (-2) + 18 \) is equivalent since it maintains the same numbers with proper signs. B \( 20 + 18 + 25 + (-2) \) is also equivalent as the order of addition doesn't affect the sum. So, the two correct options are A and B! 🎉
