Difference

The "Whole Numbers" that are between 7 and 13 are :
8, 9, 10, 11, and 12

The difference between 13 and 7 is 6

Half this difference is 3
6 divided by 2 = 3

The number ID is halfway between 7 and 13
7 + 3 = 10 or 13 - 3 = 10

definitions

Whole Number - a whole number is a number without a decimal ; must also not have any place value below 0, for e.g. tenths, hundredths, thousandths, etc.

Between - anything in the middle of things. for e.g. my desk is between Diana and Kathryn in math.

Difference - how many numbers it takes to get from one number to another. 7 and 13 would be 6 because it goes 7,8,9,10,11,12,then 13, 6 numbers to get from one to the other.

Halfway - a word used to describe something that is divided into 2 equal parts.
