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

No, it could be a partial sum.

If the sum of the numerators is greater than the denominator the sum is greater than 1. If the sum of the numerators is equal to the denominator the sum is equal to 1. If the sum of the numerators is less than the denominator the sum is less 1.
If x + 4 is less than or equal to 22, that means that x is less than or equal to 18
nine less than the product of a number and two
The sum of a number times 3 and 27 is greater than or equal to 15.

2x + 1 is equal to or less than 13.
