Question

Compute the most rational way.

Answer 1

The most rational way to solve this would be to combine like terms:

268*82 + 268*17 = 268*99
Then you get: 268*99 - 168*99
From here: Combine like terms *AGAIN*
100*99

100*99 = 9900

Answer 2

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
