Question

check the following addition. if the answer is incorrect, find the correct answer.
\

$$\begin{align*} &\\quad\\ \\ \\ 8\\ 0\\ &\\quad\\ 169\\ &\\quad\\ 315\\ &\\ +\\ 386\\ \\hline &\\quad\\ 859\\ \\end{align*}$$

select the correct choice below and, if necessary, fill the answer box to complete your choice.
a. the answer 859 is correct because re - adding from bottom to top gives the same answer.
b. the answer 859 is incorrect because re - adding from bottom to top gives the correct answer

Explanation:

Step1: Add the numbers

First, we add the numbers: \(80 + 169 + 315 + 386\)
First, \(80 + 169 = 249\)
Then, \(249 + 315 = 564\)
Then, \(564 + 386 = 950\)

Step2: Compare with 859

We got \(950\), but the given answer is \(859\), so the answer \(859\) is incorrect. Re - adding from bottom to top (i.e., \(386+315 + 169+80\)): \(386+315 = 701\), \(701+169 = 870\), \(870 + 80=950\), which is the correct answer. So option B is correct.

Answer:

B. The answer 859 is incorrect because re - adding from bottom to top gives the correct answer 950
