The difference between solving equations in primary school mathematics and before
Solving equations in primary school mathematics is very different from before.

In the past, the equation was solved by shifting terms, although it was also based on the properties of the equation, but the process was omitted. Now primary schools use the properties of the equation to solve the equation, that is to say, both sides of the equation are added or subtracted, multiplied or divided by 1 non-zero number, and both sides of the equation are equal. To solve this equation.
