sql - How to calculate Sum of 2 Count(*) in Mysql -


i have 2 tables count rows of them. 

select count(*)  docgrados_directores  docgrados_directoresleido = '0' , docgrados_directoresusu = '11'   result 1  select count(*)  docgrados_lectores  docgrados_lectoresleido = '0' , docgrados_lectoresusu = '11'  result 1

i need total count (result 2). how can sum result single statement? correct syntax??

use select add scalar values returned queries:

select (select count(*)          docgrados_directores          docgrados_directoresleido = '0' , docgrados_directoresusu = '11' )         +           (select count(*)         docgrados_lectores         docgrados_lectoresleido = '0' , docgrados_lectoresusu = '11')

the above statement should return 2 result if result of both subqueries 1.
