# On the addition table what are the doubles plus one fact numbers?

## Answer

###### Wiki User

###### 02/05/2008

Doubles are the facts in which both addends are the same. For example 3+3=6.

The doubles plus one are the facts in which one addend is larger than the other by one. Examples 3+4=7, 6+7=13, 5+6=11, 3+2=5. Learning your doubles plus one should involve knowing the doubles and mentally adding the additional one.
