Alter By a Single Stroke

How can you alter the following equation by a single stroke to make it correct?

5 + 5 + 5 = 550

5 4 5 + 5 = 550

Add a diagonal line on the top left of the first plus sign to convert + into a 4. You could also put a slash through the equal sign to make ≠ (not equal) but that’s not as cool.

A Four Word Admonition

What four word admonition makes the happy person sad and the sad person happy?

The phrase, “This too shall pass.” According to Wikipedia, the well-known phrase is often attached to a fable of a great king who is humbled by these words, and to someone who is experiencing something wonderful, it can be saddening. But to one who is in the pits of despair, it is a phrase that brings relief and hope.

In other words, if a happy person is told, “This too shall pass” it will make them sad. But to a person on hard times, hearing, “This too shall pass” will cheer them up.

How?

Monopoly has two dice, and the lowest number two dice can roll is 2. The window repair came out of Wesley’s allowance and he stopped throwing his baseball in the house.
