In grade three, we learned the vertical calculation of division. First, we need to calculate the quotient and write it at the top of the vertical bar. Then, we compare each bit of the dividend with the quotient. If one digit of the dividend is less than the quotient, then we will move it down and continue to compare the next digit.

For example, we count 36÷4. First, we write down the quotient 9, and then compare each bit of the dividend with the quotient. 3 is smaller than 9, so we move 3 down to 6. 6 is smaller than 9, so we move 6 down to 0.

Now, we have moved all the dividends to the bottom, leaving only the merchants. We read these numbers from left to right, and the result is: 9 is more than 0. So, 36÷4=9+0. We can also use this method to check the vertical calculation of division.

For example, we check 48÷6. First of all, let's calculate the quotient: 48÷6=8. Then, we compare each bit of the dividend with the quotient. 8 is smaller than 6, so we move 8 down to 8. 8 is less than 6, so we move 8 down to 0. Now, we have moved all the dividends to the bottom, leaving only the merchants. We read these numbers from left to right, and the result is: more than 8 0. Therefore, we calculate 48÷6=8+0.

Advantages of learning mathematics

People who are good at math are relatively smart and savvy, and they can show their advantages in dealing with people. The faster you think, the more ways and ideas you have. Mathematics is the foundation of other disciplines, and it is easier for people who learn mathematics well to get into other disciplines. Learning software, computer, finance and other engineering majors is even more handy.

It is used everywhere in life. Nowadays, the society is an information society, and mathematical knowledge is used in financial management and computers. Mathematics can cultivate people's integrity and honesty. Mathematics pays the most attention to convincing people by reasoning, and only believes in the results of logical reasoning. Mathematics can cultivate people's tenacity and courage. Mathematics can cultivate people's overall consciousness. Mathematics can cultivate people's good character.
