With basic adding, as shown here you can use your fingers.

The sum here is 5+2. On one hand we have 5 fingers and on the other we have 5. So all we need to do is count on 2 from 5 and you're done. Works on more too. Try these:

3+4

5+2

2+1

2+3

3+1

Advanced addition

In this addition sum we see that we have to add 123 and 123. There are two ways of approaching this question, although I will take you through one.

Put 123 above 123 and put a plus sign next to the bottom one.

Firstly you have to add 3 to 3. You need to write the answer underneath the two threes =6

Secondly you have to add the 2's (20+20 just you don't write it like that) together, and write the answer underneath =4

Finally add the 1's (100+100) together and write the answer underneath= 2

Hey presto you're done, the answer is 246, how easy was that, next time we'll go into carrying!
