d) \( 12:(-3)+5= \)

Let's have some fun breaking this down! First, we tackle the division: \( 12 \div (-3) = -4 \). Now we're left with the equation \( -4 + 5 \). Adding these two gives us \( 1 \). So, the final answer is \( 1 \). Now, if you find division by a negative tricky, you’re not alone! Just remember that dividing by a negative number flips the sign. It’s like a little math dance—when you add a positive to a negative, you're really just figuring out which is the stronger partner. In this case, positivity wins!
