How can you make the following equation true by drawing only one straight line:

**5+5+5=550**

Can you figure it out?

We draw a line in the upper left corner in the first visible plus

sign from the left, transforming the "+" into a "4".

The equation thus becomes:

545 + 5 = 550,

which is indeed accurate as the rhs of the equation is equal to its lhs.
