Question

Evaluate each expression.

$24-4\times 5$

Step-by-Step Solution

Answer

The value of the expression $24-4\cdot 5$ is $4$.

Step 1. Given information.

We have an expression $24-4\cdot 5$

To find the value of the given expression.

Step 2. PEMDAS rule.

• In the presence of grouping symbols such as parenthesis or bracket, simplify expressions in those first, beginning with the innermost grouping symbol.
• In the expression, evaluate exponential expressions or absolute values in order from left to right.
• Multiply or divide in order from left to right.
• Add or subtract in order from left to right. 

If there are no grouping symbols or exponents, we multiply or divide and then add or subtract in the order from left to right.

Step 3. Calculation.

Now we simplify the given expression $24-4\cdot 5$

$\Rightarrow 24-4\cdot 5=24-20$

$\Rightarrow 24-4\cdot 5=4$       

Hence, the value of the given expression is $4$.
