Calculate: \( 12+5+(-8) \)

Let’s break it down! First, you add \( 12 \) and \( 5 \), which gives you \( 17 \). Now, subtract \( 8 \) from \( 17 \), and you get \( 9 \). So, the answer is \( 9 \)! Looking at it step by step makes it easy-peasy. Don't let negative numbers scare you! They’re just doing a little dance when it comes to addition and subtraction. Just remember, when you add a negative, it's like taking away from the positive part of the number. Keep practicing, and it’ll become second nature!
