Question

Solve the expression $0.01\times 0.1-0.001\div 10+0.01$.

Answer 1

Hint: For solving this question you should know about the general mathematical solutions and calculations. We will solve this by the standard form of solution of mathematical expressions where we solve more than one calculation like multiplication, addition, division etc. And we solve it in the order of division, multiplication first and then we solve addition and subtraction.

Complete step by step answer:
According to our question it is asked of us to solve $0.01\times 0.1-0.001\div 10+0.01$ which is a multicalculational equation here. Now, we know that the multicalculational equations are solved by the general calculations and these general calculations are always in a fixed manner. And in the manner, we solve multiplication and division first. And then we solve the addition and subtraction. And before solving we divide it into brackets and first solve the brackets which have multiplication and division terms. So, according to the method of solving this question, first we will make brackets for it, so,
$\Rightarrow \left( 0.01\times 0.1 \right)-\left( 0.001\div 10 \right)+\left( 0.01 \right)$
Now, we will solve the brackets first, so,
$\Rightarrow \left( 0.001 \right)-\left( 0.0001 \right)+\left( 0.01 \right)$
So, by solving the brackets, we get,
$0.001-0.0001+0.01$
Now, we solve the additions and the subtractions, so,
$\begin{align}
  & \Rightarrow 0.001-0.0001+0.01 \\
 & \Rightarrow 0.0110-0.0001 \\
 & \Rightarrow 0.0109 \\
\end{align}$

So, the value of $0.01\times 0.1-0.001\div 10+0.01$ is equal to 0.0109.

Note: During solving the mathematical multi calculations we always have to keep in mind that we have to always solve our question in a fixed manner. Because if we solve it without the proper procedure, then your question will definitely go wrong and it is that you may never get the correct answer. And this is an easy procedure too.
