Formula Builder - check for multiple conditions

I want to check for multiple conditions in a formula - this is what I have tried

equal($sales_stage,"Sale Closed- Lost")
and
greaterThan(strlen($lostreason1_c),0)
and
greaterThan(strlen($lostreason2_c),0)
and
greaterThan(strlen($lostreason3_c),0)

but I get this error

equal: Syntax Error (Improperly Terminated String ') and greaterThan(strlen($lostreason1_c)')32 72
