understanding of the word "within" with regards to translation in math I need a clear understanding of the word "within" with regards to translation in math. Like if I say integers of X is within the interval of 5 and 10. Does this mean: [5,10] (5≤ X ≤10)?? The reason I ask this is because in the English language if I say: "You have within 24 hours to complete the tasks I have given you"; means that I have up to the 24th hour exactly to complete the tasks which means equal to the 24th hour or less. Here is also a definitions for the word "within". : This means I can be equal to a mile in a radius of a mile and still be within a mile or inside the mile radius that is smaller than a mile which is also within a mile. So this means in math that the word "within" always translates to this inequality ≤ right??
