Facts
The answer when 2 "neighbors" are subtracted (For example 5-4= or 3-2=)
One
14 - 9 =
5
25 - 11 =
14
42 - 38 =
4
602 - 368 =
234
The answer when 2 numbers that are the same are subtracted
Zero
12 - 4 =
8
38 - 22 =
16
56 - 49 =
7
700 - 99 =
601
The correct way to subtract is top to bottom (take away) or bottom to top (count up).
Either way!
12 - 5 =
7
532 - 118 =
414
$34.92 - $2.31 =
$32.61
When do you have to borrow in subtraction?
When the top number is too small.
16 - 7 =
9
456 - 231 =
225
623 - 45 =
578
701 - 58 =
643
What you have to do when you borrow but the neighbor is a zero.
Borrow from the next neighbor. The zero becomes a 10, then cross it out and make it a 9.
17 - 9 =
8
204 - 95 =
109
$20.55 - $13.77 =
$6.78
