rewrite the statement: 19 + 7 / 2 x 6 + 1 with 2 brackets to make its total value 2.
i said 2 brackets
impatient much?
Once is enough, thank you.

(19 + 7) / (2 x 6 + 1) = 2
To rewrite the statement with brackets in order to make its total value equal to 2, we need to consider the order of operations (also known as the PEMDAS rule). The order of operations states that calculations should be done in the following sequence: parentheses, exponents, multiplication and division (from left to right), and finally addition and subtraction (from left to right).
To achieve a total value of 2, we can rewrite the statement as follows:
19 + (7 / 2) x (6 + 1)
In this case, the parentheses are placed around (7 / 2) and (6 + 1), ensuring that these expressions are calculated first, respectively. Let's solve the equation step by step:
1. Calculate 7 divided by 2: 7 / 2 = 3.5
2. Calculate 6 + 1: 6 + 1 = 7
3. Multiply the results of the above calculations: 3.5 x 7 = 24.5
4. Add the initial number (19) to the result of the multiplication: 19 + 24.5 = 43.5
Therefore, this rewritten expression does not evaluate to a total value of 2. Note that the placement of parentheses is important in the order of operations, and in this case, it does not result in the desired total of 2.
