Which is faster, the cross method or the line segment method?
Cross. Let's go

1, cross method is also called diagonal method, also called mixing rule. As a simplified solution method, it is a graphic form of the actual calculation equation. When applied to the calculation of the average value of binary mixed systems, it has obvious advantages such as simplified thinking, simple operation and fast calculation speed.

2. The line segment method is a classic skill used in mathematical operation and data analysis, and it has a near-spike effect on the calculation of mixed proportion problems.
