$\left(6+7\right)2-1$

Step-by-Step Solution

Answer

Value of $\left(6+7\right)2-1$ is 25

Step 1 - Order for simplification

To evaluate any expression involving more than one operation, follow the below order of operations:

• First evaluate expressions inside grouping symbols like parentheses ( ) or brackets [ ].
• Evaluate the exponents.
• Perform Multiplication and division from left to right.
• Perform addition and subtraction from left to right.

Step 2 - Simplify expression inside grouping symbol

To evaluate the value of the given expression, first simplify the expression inside the parenthesis and then multiply it with 2 as shown below

$\begin{array}{c}\left(6+7\right)2-1=\left(13\right)2-1\\ =26-1\end{array}$

Step 3 - Subtract 1 from 26

Now, to simplify further subtract the numbers to get

 $26-1=25$
