Good Afternoon!
Today our lesson will coverThe Rules of Subtraction AND Subtraction of multi-digit
numbers
1.) Round 567 to the nearest hundreds place.
2.) Round 67,423 to the nearest thousands place.
3.) Round 4,897 to the nearest tens place.

Let's review what we learned in the last lesson.
There are several properties of addition
COMMUTATIVE PROPERTY:
ASSOCIATIVE PROPERTY:
IDENTITY PROPERTY:
We can change the order and the sum stays the same.EXAMPLE: 4 + 6 = 10
6 + 4 = 10
We can change the grouping and the sum stays the same.
EXAMPLE: 2 + (3+ 8) = 10 (2 + 3)+ 8= 10
We can add zero and the sum stays the same.EXAMPLE: 7 +0 = 0

We add numbers together by firstLINING UP THE DIGITS
Then we need to determine if we mustREGROUP
This is how we regroup.
197+ 35

7+5=12 so we must REGROUP 12

Now, let's look at 0 in subtraction.
13 - 0 = 13
If we subtract 0 from any number, the difference is that same number.
57 - 57 = 0
If we subtract a number from itself, the difference is 0.

We need to line up the digits. Often we need to regroup.
Subtraction is similar to addition.

First, we must line up the digits.

We look at a problem here.

We begin by subtracting the ones.

Now, we can subtract 9 from 16.
In this case, we cannot subtract 9 from 6 so we need to do the following things :
ADD THEM TO REGROUP IT AS TEN ONES and
THE EXISTING SIX ONES.
LOOK AT THE TENS
PLACE AND BORROW A

Next, we move to the tens place.
Once again, we need to regroup a hundred as 10tens
since we cannot subtract 7 from 6.

We add our 10tens to the 6tens to get 16 tens.
Now we can subtract 7 from 16.

Next, we move to the hundreds place.
