This is the process of changing a band's score into a false one.

- 1/6×2×(-3)=- 1/6×(-6)= 1

This is a place that can be directly divided, and negative is positive.

Score calculation method:

When calculating and comparing complex fractions, we use direct division to get the first place of the result, that is, the first place and the second place of the first place, and then get a more correct answer.

Direct division is widely used, mainly because its method is simple and relatively easy to operate.

Direct division is mainly applicable to two kinds of problems:

First, when comparing multiple scores, under the premise of equal size, the first big number is big and the first big number is small.

Second, when calculating the score, you can get a relatively correct answer after the first calculation when the first option is different.
