Question

Consider the following addition in base 7 complete the 1st 2 step of the additional below

Answer 1

We are to complete the addition in base seven

`\begin{gathered} 24_{\text{seven }} \\ + \\ 65_(seven) \\ ---- \\ ---- \end{gathered}`

Computing the first part

`4_{\text{seven}}+5_{\text{seven}}=9_{\text{ten}}`

Converting base 10 to base 7

This gives

`9_{\text{ten}}=1*7+2*1=12_(seven)`

Hence

`4_{\text{seven}}+5_{\text{seven }}=12_(seven)`

Therefore the answer is

`12_{\text{seven}}`
