Answer 11

And @dauspex that's really not the most common or easy way to do this problem tbh

Answer 12

@JA1 why do you say so? the first step was to remove the brackets, then i basically showed him that for a sector of 3 multiplied terms, it does not matter which order of multiplication is done

Answer 13

Yes but that is the way anyone with experience doing this type of math would do it, but for someone just learning it is best to stick to PEMDAS method like so:

\[6+7\times45(6+23)\]
\[6+7\times45\times29\]
Now you multiply from left to right:
\[6 + 315 \times 29\]
\[6 + 9135\]
Now "Addition":
\[6141\]

Doing it this way is following the PEMDAS method more directly so it is easier for him to learn :) @dauspex
