Beautiful its perfect. We should also nudge the develop in the right direction with equality checking im thinking we say √10 = √g = π = 3 = e but we will use === for this and if u want o check exact values u need to use ==== and == will be to assign variables so = can be used as an operator for dedining an equation that happens to be an object.
