The three angles add up to 180 degrees.
You add up sums at the check out and you add up the discounts. Fortunately, this is all done with a calculator inserted into the checkout computer.
well, you really have to add up the sides. if you have a 7 by 34 rectangle, you add up like this; 7+7+34+34. it'll be the perimiter around the shape
you have to add
34 = 9 + 25 = 3² + 5²
The three angles add up to 180 degrees.
The sums are: 1: 15 2: 34 3: 42
You add up sums at the check out and you add up the discounts. Fortunately, this is all done with a calculator inserted into the checkout computer.
They are: 29+5 = 34
Add all the sums, then divide by the number of sums. (ie. the average.)

The partial sums method is a way to do addition in which you add up each place value separately, then add the results together. For instance, if you were adding 567 and 483, you would first add 500 and 400, then 60 and 80, then 7 and 3. You would then add the results, 900, 140, and 10, to get the answer, 1,050.
The integers are 16 and 18.
The basic idea is the same as when you estimate sums and differences of larger numbers (which may or may not be integers). You round the numbers to one or two decimal digits, then add them up.
