Hi Yen
It depends on how old you are and if you are allow to use a caculator. If you can using a calculator, the answer is simple, if you can , you need to rewrite to the follows :
³ 4 ¹5
- 1 6
----------
2 9
Start working from the back to the front or right to left. The first coloum represent single unit, the second coloum represent 10 unit,
As 5 is not enough to less 6, you need to borrow from 10 from 40, so 5 becom 15 and "40" become ''30"
1st back coloum, you get 15-6 = 9
and 2nd back coloum, you get 3-1 = 2
The answer is 29
¹7 8
+ 2 2
----------
1 0 0
Work from the back. 8+2 = 10, 0 to write as the back and you carry the 1 from 10 to 7.
7+1=8 +2 = 10
you had 100 as the answer.
Hope this help. Think you are only starting you path to Mathematics.
