That could be interpreted in different ways. Sometimes "and" means "together with," sometimes "and" means "plus."
3 - 5(2 x a) or
3 - 10a simplified
The algebraic expression can be: 3 - (2 * a * 5).
The difficulty is in the phrase "two times a and five". The assumption of 2*a*5 may be incorrect since "and" implies addition. If so, depending on how the question is understood, the answer can be one of 3 - (2 * a + 5) or 3 - (2 * a) + 5 or even 3 - (2 * (a + 5)), each of which would give a different answer.
That is why we use the parenthesis in the mathematical expressions ;)
5

The product is positive
+6
Nine less than three times a number; the initial number being represented by s.

It could be: -3/8+4x-9z as an algebraic expression
(3)(q-11) = 3q-33
+6
Nine less than three times a number; the initial number being represented by s.
As written, those are the same. For that sentence to equal 3, we need to use parentheses. (8 + 4) divided by 2 minus (1 x 3)
Three times negative 2 minus three is equal to -9
Three minus three times six plus two is equal to -13.
