Question

in the new wizards clash video game, you can earn magic points by solving tricky puzzles. you can also spend magic points to cast spells. the table shows how much your magic points change with different actions.

action	magic points
solve a goblins riddle	25
cast a shapeshifting spell	-8
solve a password puzzle	15

which action causes the greatest change in magic points?

• casting an invisibility spell
• solving a goblins riddle
• casting a shapeshifting spell

Explanation:

Step1: Find absolute values

To determine the greatest change, we find the absolute value of each magic points change.

• For casting an invisibility spell: $|-10| = 10$
• For solving a goblin’s riddle: $|25| = 25$
• For casting a shapeshifting spell: $|-8| = 8$
• For solving a password puzzle: $|15| = 15$

Step2: Compare absolute values

Now we compare these absolute values: $25 > 15 > 10 > 8$.

Answer:
