## SUBTRACTION - ESSENTIAL POINTS

1. Subtraction means to take away or deduct.  For instance Prakash has 9 pencils. Out of that he distributes 5 pencils, then pencils now Prakash has 9 – 5 = 4 pencils.
2. These are six stars.

Now if two stars are cut, four stars are left.
3. These are five apples

If out of that three apple are eaten, then 2 apples are left.  5 -3 = 2 apples.
4. If in a pond which has nine ducks, five ducks leave the pond, then four ducks are left in the pond now. 9 – 5 = 4 ducks.
5. If you take away three from seven, four is left.
6. If we subtract 3 tens and 6 ones from 8 tens and 9 ones it is 5 tens and 3 ones. 89 – 36 = 53
7. Observe these numbers - 32, 46, 26, 49, 97, 67, 91. The highest number is 97 and the lowest number is 26. If the lowest number is subtracted from highest number it is 97 – 26 = 71.
8. There are 16 pieces of chocolate. In order that 7 pieces of chocolate must be left, 9 pieces of chocolate must be eaten.
9. When five stars out of forty seven stars five stars are cut, it is four tens and two ones or 42.
10. When out of 8 tens and 6 ones, five tens and 4 ones is subtracted, as shown on abacus we would obtain 86 – 54 = 32 or 3 tens and 2 ones.
11. If you have 16 toffees and you distribute 11 toffees, then you have 5 toffees left. ( 16 – 11 )
