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.

Um, ‘putting a line through it’ works too (signifies the equation is not true)

Also works to just change equals sign to lesser than or equal to sign.
