I'm not sure what you are asking. Sums represent either an increase of one quantity by another quantity, or a combination of two quantities. Two of anything is a pair. Did you mean to ask, "What are sums of pairs?" One common use of a pair in mathematics is an ordered pair, such as (2,3). This can represent a coordinate in a graph, or it can represent a vector. If pairs represent a vector, you add the components, so (2,3) + (40,50) = (42, 53).

How do you do sums?
The answer will depend on what kind of sums.
How many multiplication sums are there for 80?
The pairs of positive integer factors of 80 are: 1 x 80 = 80 2 x 40 = 80 4 x 20 = 80 5 x 16 = 80 8 x 10 = 80 Since multiplication sums are commutative, the reverses of the sums also hold true. For example, such that 8 x 10 = 80, also 10 x 8 = 80, and so on.
How many combinations are there to make the number 80?
Infinitely many. Start with sums of two numbers: 0 + 80, 1+79, 2 + 78 etc then 0.1 + 79.9, 0.2 + 79.8, 0.3 + 79.7 etc then 0.001 + 79.99, 0.02 + 79.98 etc and so on. Then you can have sums of 3 numbers. and of 4 numbers, etc You can also have irrational numbers in any of these sums.. To increase the number of options you can include negative numbers or subtractions: 81 - 1, 82 - 2, etc and so on with decimal fractions and irrationals in pairs, triplets, quartets, etc. And throw in multiples. An infinite number of pairs, triplets etc.
What are all the sums that make 24?
all the sums are 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,and 24
How many degrees are in the sum of an interior and an exterior angle of a regular hexagon?
Each pair of interior and exterior angle sums to 180 degrees. Since a hexagon has 6 such pairs, the sum is 6*180 = 1080 degrees.
What is to different pairs of decimals whose sums are 14.1 one pair should involve regrouping on math?
The two different pairs of decimals whose sums are 14.1 and one pair involves regrouping on math are 8.4 and 5.7.
What are the different ways you can make twenty-four?
There are infinitely many ways. First consider sums of two numbers: 12 + 12, 11 + 13, 10 + 14, ... , 1 + 23, 0 + 24, -1 + 25, -2 + 26, ... Then cosider numbers to 1 decimal place (dp): 11.9 + 12.1, 11.8 + 12.2, ... then pairs of numbers to 2 dp, 3 dp and so on, to infinitely many decimal places. That's sums of pairs of number done. Next consider sums of triplets, and then quartets, quintets, and so on, to infinitely many numbers. So that's sums dealt with. Now start with multiplications. In much the same way as with addition, there are infinitely many pairs, triplets and so on. After that you can start looking at exponential, inverse, logarithmic, trigonometric functions.

What are equivalent fracations?
Equivalent fractions are fractions whose results are equal to each other. For example, 3/4 (three quarters) and 6/8 (six eighths) are equivalent fractions, because the answer to both their sums is 0.75.Any two pairs of numbers expressed as a vulgar fraction whose sums are equal to each other can be considered equivalent.
What are all the sums that make 24?
all the sums are 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,and 24

How is the mean calculated?
Add all the sums, then divide by the number of sums. (ie. the average.)
How many different sums can you make from 5 numbers?
you can make at least 25 sums
Emily worked out all the sums in her head?
Emily worked out all the sums mentally.
Which is the only number which is equal to the sum of its digits?
Well, 1 is equal to 1. 9 is equal to 9. So any number from 0 to 9. I do not think this is what is meant by the question. If you mean any number with more than one digit. There is no such number. Because 11 sums to 2. 19 sums to 10. 21 sums to 3. 29 sums to 11. 111 sums 3. 119 sums to 11. The sums do not grow as fast the increase of digits.
