Calculate: a) \( (-8)+5 \) d) \( 12+(-7) \) g) \( 3+4 \)

The first calculation, \( (-8) + 5 \), gives us \( -3 \). Think of it like going down a steep hill and then climbing up a bit; you're still below sea level but much closer to it! Next up, \( 12 + (-7) \) equals \( 5 \). This is like having $12 and spending $7 at a store; you still have some cash left over, just not as much as before! Lastly, \( 3 + 4 \) equals \( 7 \). This one’s a classic; it's like bringing three apples and then adding four more to your basket – you’re sure to feast on a delightful fruity combo!
