00:0-1 To add a 0.17 plus 16.9 . 1st line up
00:05 the decimals in this problem , I would put 16.9
00:09 on top since it's the larger number . So we
00:12 have 16.9 plus 0.17 Notice that 16.9 has no digits
00:24 in the hundreds place so we can use a zero
00:28 to fill this position . Now we simply add the
00:31 numbers by column , starting on the right . Zero
00:35 plus seven is seven , nine plus one is 10
00:38 . So we bring down the zero and carry the
00:41 one , one plus six plus zero is seven and
00:45 one plus zero is one . Finally we bring down
00:50 the decimal , So 0.17 plus 16.9 is 17.07 .
