Short Answer

Expert verified

The value of the expression $29 - 3 (9 - 4)$ is 14.

Step by step solution

Step 1. Order of operations.

In order to evaluate an expression, the order of operations must be followed, which is:

Evaluate the expressions inside the bracket
Evaluate the powers
Multiply and/or divide
Add and/ or subtract

The evaluation takes place from left to right.

Step 2. Evaluate the expression inside the bracket.

$29 - 3 (9 - 4) = 29 - 3 \cdot 5$

Step 3. Multiply 3 by 5.

As per the order of operations, now multiply 3 by 5.

$\begin{array}{l} 29 - 3 (9 - 4) = 29 - 3 \cdot 5 \\ = 29 - 15 \end{array}$

Step 4. Apply subtraction operation.

Subtract 15 from 29.

$\begin{matrix} 29 - 3 (9 - 4) = 29 - 3 \cdot 5 \\ = 29 - 15 \\ = 14 \end{matrix}$

Therefore, the expression is equal to 14.
