Question

Calculate 3 + 77777
A. 77779
B. 77780
C. 77781
D. 77790

Answer 1

Hint: In this problem, we have to find the solution for the given calculation. Here we should add the given two terms. We can see that the first term is a single term and the second term has 4 digits. We should keep the first term below the one’s place of the second term and then we have to add the numbers. We can then add the remaining terms and find the answer for it.

Complete step by step answer:
Here we have to calculate the given terms by adding them.
The given numbers to be added are
3 + 77777
We can first arrange them in the correct order. We know that the single digit is to be placed in one's place and we have to start adding.
\[\begin{align}
  & 00003 \\
 & \underline{77777} \\
\end{align}\]
we can now add the above step starting from the ones place, we get
        \[1\]
\[\begin{align}
 & 00003 \\
 & \underline{77777} \\
 & 77780 \\
\end{align}\]
Here the one's place is added and the result is 10, in which 0 is in the bottom and the remaining one should be added to the tens place.

So, the correct answer is “Option B”.

Note: We should always remember that we should start adding the terms from one's place. If we get two digits in the one place then the digit in the one's place should be written in the bottom and the digit in the tens place should be added to the next tens place digit.
