BRIEFING TOPIC FOR NEXT WEEK: You're in Dortmund and you want to buy lots of jagaarbombs, cheap netto ameretto and an uncle toms dinner. Its the end of the month and you are poor so you borrow €50 euros from CC2 and €50 euros from CC3. You only spend €97 euros on jagaarbombs and netto goodies so you give cc2 €1 and cc3 €1 and keep a €1 for you. This means you now owe them€49 euros. So... €49 euros and €49 euros = €98 plus the €1 euro you kept where is the missing €1?
