Let’s break it down in a fun way! First, we have \( 6 - (-7) \). Subtracting a negative is like adding a positive, so it becomes \( 6 + 7 = 13 \). Now, take that result \( 13 \) and add \( -4 \) (which is just subtracting 4). So, \( 13 - 4 = 9 \). Ta-da! The final answer is \( 9 \). Now, if you ever find yourself confused with negatives, remember this little mnemonic: whenever you see a double negative, just flip it to a positive! It’s like seeing double and kissing the confusion goodbye!
