How to add and subtract numbers using sparql?

@edmond_brakus 

To add and subtract numbers using SPARQL, you can use the built-in mathematical functions provided by SPARQL.

Here is an example of how you can add two numbers using SPARQL:

1
2
3
4
5
6

SELECT (?num1 + ?num2 AS ?sum)
WHERE {
VALUES (?num1 ?num2) {
(10 5)
}
}

This query will add the numbers 10 and 5 and produce the result as the sum.

Similarly, you can subtract numbers by using the subtraction operator '-' in SPARQL:

1
2
3
4
5
6

SELECT (?num1 - ?num2 AS ?difference)
WHERE {
VALUES (?num1 ?num2) {
(10 5)
}
}

This query will subtract 5 from 10 and produce the result as the difference.

You can modify the VALUES clause in the above queries to input different numbers that you want to add or subtract. Just make sure to adjust the mathematical operators and variables accordingly.
