How to calculate the vertical form of the first grade of mathematics now

? What do you mean?

Regardless of addition and subtraction, when the columns are vertical, they must be flush, with one digit flush and with ten digits flush. There should be no hundred digits in the first grade. ) Even if there is, all the figures are straight flush. Write the addition and subtraction sign on the left, counting from one digit, from one digit to ten digits, and so on. ...

Why do you feel dizzy when you answer such a naive question?
