There were 275 sheep on Ben's farm.
He sold 167 sheep to his neighbor.
How many sheep were left on his farm?

In this problem, I will subtract 167 from 275; so

275 - 167 = ?

First, I will subtract 100 from 200:       200 - 100 = 100
Then, I will subtract 60 from 70;            70 -   60 = 10
Finally, I will subtract the ones, 5 - 7 but it is not possible because 5 is smaller than 7, 
 so I will add 10 to 5 to make it 15; now I can subtract 7 from 15, so 15 - 7 = 8.

Then, I will add 100 to 8: 100 + 8 = 108

So, 108 sheep will be left on Ben's farm

Ben has 165 chickens and 47 ducks
on his farm. How many birds are there
on his farm all together?

60 + 40 = 100

100 + 0 = 100 

100 + 100 + 11 = 211

First I added the tens (60 + 40 ) = 100
Next, I added the ones (5 + 7) = 12
Then I added 100 + 100 + 12 and I got 212

So Ben had 212 birds on his farm altogether.

A company in Wanganui
has made 80 million face
masks. ½ of the masks will
be distributed to the Auckland
region, ¼  to the South Island
and the rest to all other parts
of the North Island. How many
masks will be distributed to
the South Island?

1/4 of 80 =  

So I divided 80 by 4, 80/4 =20 

So 20 million masks will be
distributed to South Island
