Reviewing Comparison Operators

Below is a recap of the comparison operators we've covered:

Operation	Symbol	Usage Example
Equality	`==`	`a == b`
Inequality	`!=`	`a != b`
Greater than	`>`	`a > b`
Less than	`<`	`a < b`
Greater than or equal to	`>=`	`a >= b`
Less than or equal to	`<=`	`a <= b`

You'll be using some of these operators in the upcoming task.

Task

Swipe to show code editor

Insert the appropriate inequality symbol (either < or >) so the expression evaluates to 1.
