• There is a big difference between saying someone has `5 more dollars` and saying someone has `5 times more dollars`. You would add/subtract for the first one, but multiply/divide for the second one.
• Couldn't you just subtract 33 from 5
• No, you can't because you'll get a negative value when you say "Subtract 33 from 5" The equation is 5-33 (ask what is subtract 33 from 5 to Google, it shows -28)
