Evaluate the expression

$5.8\left(3\right)+3\left(1.1\right)$

Short answer

The value of expression is$20.7$.

Step-by-step solution

Step-1 – Order of operations

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 – Multiply the numbers from left to right 

To evaluate the given expression, first multiply the numbers from left to right as shown below

$\begin{array}{c}5.8\left(3\right)+3\left(1.1\right)=17.4+3\left(1.1\right)\\ =17.4+3.3\end{array}$

Step-3 – Add the numbers

Now, to simplify further add the resulting numbers to get

$\begin{array}{c}5.8\left(3\right)+3\left(1.1\right)=17.4+3.3\\ =20.7\end{array}$

So, the value of the expression is $20.7$.
