Question

Evaluate 20 + 16 ÷ 2 − 5. 13 18 14 23

Answer 1

23.

Explanation:

The expression “20 + 16 ÷ 2 − 5” follows the order of operations, also known as BIDMAS or PEMDAS. This stands for Brackets, Indices (or Exponents), Division and Multiplication (from left to right), Addition and Subtraction (from left to right).

Let’s break it down:

First, perform the division: 16 ÷ 2 = 8

Then, substitute this back into the equation: 20 + 8 - 5

Perform the addition: 20 + 8 = 28

Finally, perform the subtraction: 28 - 5 = 23

So, 20 + 16 ÷ 2 − 5 equals 23.

Answer 2

To evaluate the expression 20 + 16 ÷ 2 - 5, we follow the order of operations, which is often remembered using the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

First, we perform the division: 16 ÷ 2 = 8.

Then, we perform the addition and subtraction from left to right: 20 + 8 - 5 = 28 - 5 = 23.

So, the answer to the expression is 23.
