if I went to draw a rectangle that is 50[br]pixels tall and that is twice as wide as

0:00:13.599,0:00:15.009
it is tall

0:00:15.009,0:00:19.960
how would I programmed the computer to[br]do that well I could tell the artist to

0:00:19.960,0:00:25.990
go up 50 turn right and then go over 100[br]and move the whole thing twice but then

0:00:25.990,0:00:31.150
i'm doing the math for the computer[br]multiplying 50 x 2 in your head may not

0:00:31.150,0:00:36.220
be that hard but computers are really[br]good doing that so we should leave it to

0:00:36.220,0:00:41.140
them whenever possible if I just use the[br]variable called height instead then I

0:00:41.140,0:00:46.540
could easily change height 250 and then[br]change my algorithm to tell the artist

0:00:46.540,0:00:52.989
to go up by height turn right and then[br]go over x height x 2 which gives us a

0:00:52.989,0:00:55.720
rectangle that is twice as wide as it is[br]tall
