In the elementary schools, we are asked to solve equations with the assumption that operators are already given. For example: **"4 `+` X = 5"**, or **"6 `-` X = 9"**, etc., mostly with the already defined operators, like **`+`, `-`, `*`,...** etc. However, what's more useful in real life, is the creativity and operation search. So, instead of providing **`+`, `-`, `*`, `÷`, `∫`, `∇`,...** etc. as given, teach kids to do operation search to satisfy conditions defined by the equality sign.

For example, **"4 `?` = 5"**, meaning, -- what can we do with **"4"** to get **"5"**. Or **"6 `?` = 9"** -- what can we do with **"6"** to get **"9"**? Now, replace the numbers with real situations in kids' lives, and teaching operation search math can help them, fostering their creativity rather than life in one axiomatics of mathematics.

And, perhaps the question mark is not the best symbol here, as it is directional. Something like an infinite-dimensional circular question mark around one side of equation would be more appropriate.

在小學校，要求我們在已經給出運算符的前提下解方程。 例如：**"4 `+` X = 5"**或**"6 `-` X = 9"**，等等。大多使用已經定義的運算符，例如**`+`, `-`, `*`,...**等。然而在現實生活中更有用的是創造力和操作搜索。 因此，與其提供給定的**`+`, `-`, `*`, `÷`, `∫`, `∇`,...**等，不如教孩子進行操作搜索以滿足等號定義的條件。

例如，**"4 `?` = 5"**，意思是用**"4"**做什麼可以得到**"5"**。或是**"6 `?` = 9"**——用**"6"**怎麼得到**"9"**？現在，將數字替換爲孩子們生活中的真實情境，操作搜索數學教學可以幫助他們，培養他們的創造力，而不是生活在數學公理中。

而且，問號可能不是這裏的最佳符號，因爲它是有方向性的。像在等式一側的無限維圓形問號之類的東西會更合適。
