Transform the following natural language expressions into numerical expressions and calculate the corresponding number: A) subtract the square of number 5 from twice the addition of 3 and 9 B) the product between the number 2 and the square root of its successor

A) Let's first transform the expression "subtract the square of number 5 from twice the addition of 3 and 9" into a numerical expression and then calculate it.

The expression can be written as: 2 \cdot (3 + 9) - 5^2

Now, let's calculate it:
2 \cdot (3 + 9) - 5^2 = 2 \cdot 12 - 25 = 24 - 25 = -1

Therefore, the result is -1.

B) The expression "the product between the number 2 and the square root of its successor" can be written as: 2 \cdot \sqrt{2 + 1}

Now, let's calculate it:
2 \cdot \sqrt{2 + 1} = 2 \cdot \sqrt{3} = 2\sqrt{3}

Therefore, the result is 2\sqrt{3}.

\textbf{Answer: }
A) -1
B) 2\sqrt{3}
