Okay. There's one more useful operator related to division: the modulo operator (%). It returns the remainder of one number divided by another number, like this:

x % y

For instance, 9 % 7 will return 2, because 9 / 7 is 1 with 2 as the remainder. This operator works with integer and decimal numbers.


In our game, you can increase your strength by 1 if you sacrifice 7 HP. For each character, show its name and calculate how many health points will be left if the player decides to sacrifice the maximum number of HP. Name the column hp_left.

Stuck? Here's a hint!

Use this expression: hp % 7.
