In primary school mathematics, fill in the same number □ 9 △+○△□ =○△□ 9 with the same shape.
First of all, you can definitely see that the circle is 1 at a glance, because numbers can only enter 1. After knowing that the circle is 1, you must know that 1 on the right must be added with 9 to enter 1, so the square is 999 △+ 1 △ 9 = 1 △ 99.

If it is 999+199 =1198.

So the triangle on the right can only be 0, it can't be a twist.

So the triangle is 0, so it is 990+ 109= 1099.
