SAY I BORROW 50 DOLLARS FROM MY DAD AND 50 DOLLARS FROM MY MOM. NOW SAY I SPEND 97 DOLLARS. NOW SAY THAT WITH THE THREE DOLLARS I HAVE LEFT, I GIVE ONE TO MY DAD AND ONE TO MY MOM SO THAT I OWE THEM 98 DOLLARS IN TOTAL. IF I OWE THEM 98 DOLLARS, AND I
HAVE 1 DOLLAR LEFT OVER, WHERE’S THE LAST DOLLAR?
