Lets get started :)
268 · 82 + 268 · 17 - 168 · 99
Let us do each separately as it is more ideal
268 ( 82 ) = 21976
268 ( 17 ) = 3556
168 ( 99 ) = 16632
Just a little reminder, there are no like-terms since it does not contain variables
21976 + 3556 - 16632
We need to take a look at the order of operations
Addition comes before subtraction
= ( 21976 + 3556 ) - 16632
= 26532 - 16632
Now we do the final step
= 9900
