Hey! The most intuitive way I've been explained the idea of subtracting negative numbers is in terms of debts. <em>Subtracting</em> a debt from your bank account has the effect of <em>adding </em>money to it. Imagine you had $10 in your account, but you owed $8 in debt; your current balance would show $2 in your account. If you <em>took away that debt</em>, though, you'd be back up to $10. If we imagine your funds as positive numbers and your debts as negative numbers, we could express taking away that debt as:
2 - (-8) = 10
Hope that makes a little more sense!
