a) \( 8:(-4)+1= \)

Let's break it down! First, you start with \( 8 \div (-4) \), which equals \( -2 \). Then, add 1 to that result: \( -2 + 1 = -1 \). So, the final answer is \( -1 \). Now, if you ever find yourself in a situation where negative numbers are involved, remember to pay extra attention to signs! Mistakes often happen when adding or subtracting these sneaky negatives, so double-check your calculations to avoid any slip-ups.
