Since subqueries are not allowed in views, you will need to simulate them by creating multiple views.
For example, this query will solve your issue if directly executed:
SELECT
TotalCircles + TotalSquares AS TotalShapes
FROM
(SELECT
BlueCirles + RedCircles AS TotalCircles,
BlueSquares + RedSquares AS TotalSquares
FROM
(SELECT
2 AS BlueCirles,
3 AS RedCircles,
4 AS BlueSquares,
5 AS RedSquares
) AS shapes
) as totals;
According to the MySQL documentation views have the restriction on not being able to contain subqueries in the FROM clause. To work around this limitation and turn this query into a view, break it up into 3 views (one for each subquery) with the last giving the desired combination of fields:
CREATE VIEW shapes AS
SELECT
2 AS BlueCirles,
3 AS RedCircles,
4 AS BlueSquares,
5 AS RedSquares;
CREATE VIEW totals AS
SELECT
BlueCirles + RedCircles AS TotalCircles,
BlueSquares + RedSquares AS TotalSquares
FROM
shapes;
CREATE VIEW result AS
SELECT
TotalCircles + TotalSquares AS TotalShapes
FROM
totals;
SELECT * FROM result;
