[n] can mean greatest integer function (floor function) so knowing what is meant is important

OpenStudy (amistre64):

place the number in the [ ] along the number line; and since this is floor; pick the integer that is under it

OpenStudy (amistre64):

|dw:1323619009933:dw| -1 is the floor

OpenStudy (anonymous):
