Where did you use 0 in elementary school? Tell me about your understanding of 0.

Three apples, eat three, 3-3=0, two identical numbers are subtracted to get 0, and 0 means no.

When the temperature is 0, water freezes, but the temperature can still drop; The sum of two opposite numbers 0, 0 is a dividing number.

A car hasn't started yet, the driving distance is 0, and the car has been driving for 3 kilometers. 24 hours a day, 0 is the beginning of the day, where 0 represents the starting number.

Add a 0 after 2 to become 20, and add a 0 after a positive integer to expand the original number to 10 quilt.

Adding a 0 after -2 becomes -20, and adding a 0 after a negative integer reduces the original number by 10 times.

0.2 followed by a 0 becomes 0.20, which is the same size, but the counting unit is changed from one tenth to one hundredth.

205, the 0 in the middle of 1006 is a placeholder, indicating that this digit has no digits.

In the vertical calculation of division, there is not enough quotient 1 on a certain digit, so it is occupied by 0.

When doing division, both the dividend and the divisor have zeros at the end. According to the property of quotient invariance, the dividend and divisor can be divided by the same number of zeros at the same time, so the calculation is relatively simple, but the remainder must be supplemented by the number of crossing zeros.

Pure decimals, such as 0.23, where 0 before the decimal point means that there is no number in the integer part, and all pure decimals are less than 1.

0 cannot be divisible because 6÷0=? No number is multiplied by 0 to get 6, so it cannot be calculated.

Because the sign of fractional sum ratio is equivalent to the sign of division, the denominator of fractional sum ratio cannot be 0.
