PROPERTIES OF SUBTRACTIONS (BLOG 12)
Good morning boys,
Today we are going to learn the properties of subtractions.
There are some facts related to subtraction. These facts are called the properties of subtractions.
1. A number - 0 = The same number
Eg. 5 - 0 = 5
11 - 0 = 11
2. A number - 1 = its predecessor
Eg. 10 - 1 = 9
455 - 1 = 454
3. We cannot interchange the order of the minuend and the subtrahend.
Minuend 4 7 3 1 8 3 4 1 1 8
Subtrahend - 3 4 1 1 8 - 4 2 1 0 6
Difference 1 3 2 0 0 not possible
4. Minuend - Subtrahend = difference
Minuend - Difference = Subtrahend
Eg. Minuend - 8 9 8
Subtrahend- 4 5 0
Difference- 4 4 8
