What is 2+3?

2 plus 3 is 5, which is the complete 5 plus in abacus.

The formula of five plus abacus calculation is: five to four once, five to three twice, five divided by two three times and five to one four times.

For example, if you dial 4 on the abacus, you can't dial 3 directly. Let's dial 5 first and then add 2. Then we dial 2 to get 7, which is three times five plus two.

4+2, you dial 4 on the abacus, but you can't dial 2 directly. Dial 5 first, then add 3, and then dial 3 to get 6, which means 2 times, 5 times and 3 times.

I hope it can help you solve the problem.
