That would be equal to the sum of all natural numbers less than or equal to 100 minus the sum of all natural numbers less than or equal to 89.
The sum of all natural numbers less than or equal to x can be calculated with this equation:
x
∑n = n(n + 1) / 2
n=1
We can take the numbers given above then, and plug them into that sum, giving us the equation:
x = 100(100 + 1)/2 - 89(89 + 1) / 2
x = 5050 - 4005
x = 1045
