​Addition

​To be continued

​Take over is important part of life.

For example-7+3=10

So, for instance 27+33=510 is wrong. For this, we use take over.

​

Addition is used in daily life.​

​In here, we have take over for 27+33=60. In 7+3=10 we have take over 1 in the other side (tens place) and add 2+3+1(extra here) and we got 6.

​

​

​Addition can't be done without take over.
