Total number of baseball cards Jessica has = 1368 cards.
Total number of baseball cards Thomas has = 1633 cards.
We need to find who has more baseball cards.
We can see 1633 is greater than 1368, because we have hundreds digit in 1633 is 6 and hundreds digit in 1368 is 3.
6 is greater than 3. Therefore 1633 is greater than 1368.
And finally we could say Thomas has more baseball cards than Jessica has.
