When a number ends in 0-4, you round back to 0.  For example, rounding to the nearest "10":  151 would round to 150; 1293 would round to 1290.  For numbers ending in 5-9, round up.  165 becomes, as ROMOS said, 170.  99 would become 100.  Rounding those same numbers to the nearest 100:  151 = 200, 1293 = 1300; 165 = 200, 99 = 100.  You look at the number to the right of the place value to which you are rounding.
