Short Answer

Expert verified

The value of this expression is 13.

Step by step solution

Step 1. Use the order of operations.

The order of operations is the sequence of steps with which we solve any given algebraic expression, order is as follows:

Step 1: Evaluate the expressions inside grouping symbols.

Step 2: Evaluate all powers.

Step 3: Multiply and/or divide in order from left to right.

Step 4: Add and/or subtract in order from left to right.

Step 2. Solve the expression.

We are given that the expression $3 + 16 \div 8 \cdot 5$

Since expression has both multiplication and division, we proceed from left to right.

First, we perform division as shown:

$\begin{array}{l} 3 + 16 \div 8 \cdot 5 \\ 3 + 2 \cdot 5 \end{array}$

Next, we perform, multiplication:

$3 + 10$

Lastly, we perform addition

$\begin{array}{l} 3 + 10 \\ = 13 \end{array}$

Thus the answer is 13.
