Since this is pre- algebra I do realize that you mean. The answer is 13 :D
When a plus sign (+) and a minus sign (−) are next to each other, they combine to form a minus sign (-) if the plus sign is considered as a positive quantity. In mathematical terms, this can be expressed as + - = - or simply as subtracting. If they are part of an expression, their relationship depends on the context of the numbers or variables they are associated with.
It is called a term.
An algebraic term.
Each part of an algebraic expression separated by a plus or minus sign is called a "term." Terms can consist of constants, variables, or a combination of both, multiplied together. For example, in the expression (3x + 5 - 2y), the terms are (3x), (5), and (-2y). The operations of addition and subtraction indicate how these terms are combined in the expression.
The math term for each part of an algebraic expression separated by a plus or minus sign is called a "term." In an expression like (3x + 4y - 5), the individual components (3x), (4y), and (-5) are all considered terms. Each term can consist of a coefficient, a variable, or a combination of both.
They are terms of an algebraic expression
Yes and the parts are terms of the expression.

The factor expression of ( 11pqr ) is simply its prime factorization along with the variables, which can be expressed as ( 11 \times p \times q \times r ). Each component—11, p, q, and r—represents a factor of the expression. There are no further factors to simplify since 11 is a prime number and p, q, and r are treated as distinct variables.
To write an expression for the area of a rectangle, use the formula (A = l \times w), where (l) is the length and (w) is the width. You can express this in different ways, such as (A = w \times l) or (A = l^2) if it's a square where (l = w). To find the area, simply substitute the values of length and width into your chosen expression and calculate the result. For example, if (l = 5) and (w = 3), then (A = 5 \times 3 = 15) square units.
