What Is It ????
Range is the difference between the lowest number and the highest number. Say the numbers 5,10,15,20... the lowest is 5, and the highest is 20...then subtract 5 from 20.. 20-5=15! 15 is the range of 20 and 5. Now you try, the numbers, 8,12,34,78... do you have the number?? If you are correct you should have gotten the number 70! If you are having a little trouble, try it again with different number sequences, ask a friend who understands, or go to the website below! Keep practicing and you'll get it in no time!!
