App Description

There are Numbers, Arithmetical symbols(+-×÷) and Equal symbols in the 5×5 matrix!
They are in random place, MAKE THEM IN RIGHT PLACE!

PS:
① Level 1 (Horizontal Mode) : Formulas can only be read from left to right, which means "1-2" and "2-1" are different.
e.g.
1 + 1 = 2
2 = 3 - 1

② Level 2 (Vertical Mode) : Formulas can only be read from top to bottom.
e.g.
1 3 1
+ - =
1 , 2 , 2
= = -
2 1 1

③ Level >2 (Hybrid Mode) : Formulas can be read from both way.
e.g.
1 2
+ -
1 + 2 = 3 , 2 = 1 + 1
= =
2 1
