How does the 10-key calculator work?

[bliebert]

Every time I add two numbers and hit enter it's just giving me a result of the original number!

pretty much same as a "standard 10-key.

If you have to add number 1 2 and 3

You enter

1 +

2 +

3 +

=

It's different from the math operation 1 + 3 = 4

it's 1 + 3 + = 4

Similar for substraction

for 4 - 3 + 2 you enter

4+

3-

2+

=

(Oh, I presumed you were asking the function of 10-key in Lacerte.

Isn't it how you use your Sharp or TI Ten-key?
