i have two green ballsand three purple balls so how many ballsdo i have altogether? so two green ballsand three purple balls is going to be 5 balls altogether. we can count them; one, two, three, four, five. now what if we did somethinga little different? let's start with the five balls,and let's take away two. let's subtract two of these balls. take away one and two,and what are we left with?
we are left withone, two, three balls. we're left with three balls. you might see a pattern here;two plus three is equal to five but if you start with fiveand take away two, you're going to be left with three. look how they're arranged. two plus three is equal to fiveand five minus two is three. it works the other way around. if i start with fiveand i were to take away three,
if i subtract one, two, three,what am i left with? i'm left with one, two,i'm left with two. so two plus three is five,three plus two is five, which is another way of sayingthat five minus two is three, or five minus three is two. take a look at this, it's a really important idea to understand in math. if you add two numbersand you get another number, then you take the resultand subtract one of these
you're going to get the other number.
