Question

34.95 + 240.016 + 23.98 =?

Answer 1

Hint: In this problem, we have to calculate the given addition problem, with decimal numbers. We should solve this problem by adding the given numbers. We can first arrange them in order according to the decimal points. We can then add it from the one's place. If we get a resulting number as two digits in one place, we can place the number in one's place bottom and the tens place number above the next number. Similarly we can solve for each step.

Complete step by step answer:
Here we have to add the given numbers.
34.95 + 240.016 + 23.98
We can see that the given numbers are decimal numbers.
We can now arrange them in order, we get
\[\begin{align}
  & 034.950 \\
 & 023.980 \\
 & \underline{240.016} \\
\end{align}\]
Here we have added some terms as zero to arrange the decimal numbers orderly in this way.
We can now add the numbers in the ones place, we get
\[\begin{align}
  & 034.950 \\
 & 023.980 \\
 & \underline{240.016} \\
\end{align}\]
              \[6\]
We can now add the numbers in the tens place, we will get 5 + 8 + 1 = 14, where we can write 4 in the tens place and one can be added to the hundreds place.
\[\begin{align}
  & 034.\overset{1}{\mathop{9}}\,50 \\
 & 023.980 \\
 & \underline{240.016} \\
\end{align}\]
            \[46\]
We can now add the one in the top of the hundreds place with the remaining numbers and put the decimal point,
\[\begin{align}
  & 03\overset{1}{\mathop{4}}\,.\overset{1}{\mathop{9}}\,50 \\
 & 023.980 \\
 & \underline{240.016} \\
\end{align}\]
       \[.946\]
Similarly, we can add the terms, we get
\[\begin{align}
  & 034.950 \\
 & 023.980 \\
 & \underline{240.016} \\
 & 298.946 \\
\end{align}\]
Therefore, the answer is 298.946.

Note: We should always remember that, if we have decimal numbers for any of the operations, we should know how to arrange them in order with decimal points. We should also remember to add the remaining number from the previous term. This method will differ in subtraction.
