Some calculations in the second grade of primary school are mainly basic calculations, which are difficult for primary school students to access. Its content is roughly the calculation of multiplying two digits by one digit, and dividing two digits by one digit (table division). How to write the second grade vertically;

Now let's use a multiplication and two division problems to demonstrate:

2/7

As shown in the figure, it is very simple to punish two digits with one digit. When calculating, the numbers should be aligned and the carry should be written clearly to avoid forgetting when adding.

In this 24/6 problem, the columns are vertically aligned, and we know that it is 4624, so the quotient 4 of this problem is divisible.

The last question has a remainder. Two or three get six; 3? 2 is inexhaustible, leaving 1.

In the division of the second grade, you don't have to deal with the remainder, just write it down.

If you don't buy it, it's really gone. 29 yuan's math training class was held only after 9 class hours.

After the demonstration, let's study together!
