Teacher Charmain stands in front of a big screen. On the screen, a place value chart appears with columns from left to right that read "Hundreds, tens, ones, decimals, tenths, hundredths, thousands."

Teacher Charmain is in her twenties, with brown hair in a low ponytail. She wears jeans and a blue Homework Zone T-shirt.

She says HI, TVOKIDS.
IT'S TEACHER
CHARMAIN HERE.
TODAY WE'RE GOING TO
ADD LARGE NUMBERS,
BUT WITH DECIMALS.
SO, WE'RE GOING TO
DO A TWO-DIGIT BY
TWO-DIGIT ADDITION
WITH A DECIMAL IN IT.
DON'T BE FRIGHTENED.
A DECIMAL DOESN'T
REALLY CHANGE MUCH
OF WHAT YOU
ALREADY KNOW.
SO, LET'S DO A
NUMBER TOGETHER.
HOW ABOUT IF WE DO
THIRTY-TWO AND
FORTY-THREE HUNDREDTHS.

She puts a 3 in the tens column, a 2 in the ones, a period in the decimal columns, a 4 in the tenths and a 3 in the hundredths.

She says AND, WE'RE GOING
TO ADD THAT TO...
ELEVEN AND
FIFTY-EIGHT HUNDREDTHS.

She puts a 1 in the tens column, a 1 in the ones, a period in the decimal column, a 5 in the tenths, and an 8 in the hundredths column.

She says SO, I'M GOING TO PUT
MY EQUAL SIGN HERE,
SO THAT ANYTHING
UNDERNEATH THAT
IS GOING TO BE MY
SUM AS MY ANSWER.
SO, THE FIRST THING
WE'RE GOING TO DO
IS START OVER IN
THE HUNDREDTHS' COLUMN
BECAUSE THAT'S WHERE
THE LAST DIGITS ARE,
AND WE'RE GOING TO ADD
THOSE TOGETHER NORMALLY.
WE'RE GOING TO COMPLETELY IGNORE
THE DECIMAL AT THIS POINT.
WE'RE GOING TO ADD THREE PLUS
EIGHT WHICH IS ELEVEN.
I'M GOING TO PUT
THE ONE HERE,
AND I HAVE TO
CARRY OVER THE TEN
FROM THE ELEVEN INTO
THE TENTHS' COLUMN.
I'M GOING TO ADD THE THREE
DIGITS IN THE TENTHS' COLUMN,
SO ONE PLUS FOUR
IS FIVE,
AND FIVE PLUS FIVE
IS TEN.
I PUT THE ZERO HERE
FROM THE TEN AND THEN
I'M GOING TO CARRY IT OVER
TO THE ONES' COLUMN HERE.
NOW, I HAVE THIS
DECIMAL HERE AND
IN ADDING, WE CAN JUST
PUT THE DECIMAL HERE.
IT'S NOT GOING TO
CHANGE OR MOVE
FROM WHERE IT
ALREADY IS.
WE KNOW THE DECIMAL
IS GOING TO BE THERE
NO MATTER WHAT.
SO I CAN CONTINUE
MY ADDING.
I'VE GOT THE THREE DIGITS:
ONE PLUS TWO WHICH IS THREE,
AND THREE PLUS ONE
WHICH IS FOUR.
AND THEN IN MY TENS' COLUMN,
I HAVE THREE PLUS ONE
WHICH I KNOW IS FOUR.
AND THAT GIVES ME
MY COMPLETE SUM.
AND MY ANSWER IS FORTY-FOUR
AND ONE HUNDREDTHS.
SO REMEMBER WHEN YOU'RE
ADDING WITH A DECIMAL,
THE DECIMAL GOES IN
THE EXACT SAME PLACE
IN YOUR SUM AS IT IS
IN THE ADDITION PART.
SO YOU DON'T HAVE TO
MOVE IT OR ANYTHING.
IT STAYS RIGHT
WHERE IT IS.
AND YOU JUST ADD LIKE
YOU NORMALLY WOULD
AND CARRY AS YOU
NORMALLY WOULD.
GOOD LUCK WITH YOUR
DECIMAL ADDING.
THANKS, TVOKIDS.
