It is a practice app for calculation problems of simultaneous equations in important fields in the second year of junior high school.
There is an intermediate formula for the answer to each problem, and there is also an explanation of how to solve it with an example, so it is safe for those who have just learned or who are not good at calculating simultaneous equations.

Computational problems can be solved accurately by practicing a lot of amounts.
Let's repeat the basic problems and acquire the ability.

In addition, even though simultaneous equations are calculation problems, difficult questions are also asked for high school entrance examination problems. Practice well and make sure you can solve it.
