At which age do you think an average child can perform the arithmetic operation 48 + 67 for example?

I mean like this:

1

48

+67

___

115

What about an intelligent child? A genius child (like Albert Einstein)?

At 7 or 8. I suppose that a gifted child could probably master this at 5.

Using paper and pencil, a first grader could probably solve that problem if they truly try. A genius child could probably do it as soon as they can write.

Are you serious? How old are you?

40+60=100 and 8+7=15

100+15=115

DUH?
