What is the use if:false and if:true in LWC?

template if:true in LWC is used for Conditional Rendering to display markup or DOM elements dynamically if true value is provided. template if:false works in the same way but with the false value. But template if:true or template if:false does not support the Conditional Statements. For example, we can write template if:true={boolVariable} but we can not write template if:true={number>10}.
