The = sign
When an expression is expanded, its value remains the same; however, the form of the expression changes. Expansion involves distributing and simplifying terms, which can make the expression more straightforward to understand and manipulate. For example, the expression ( (x + 2)(x + 3) ) expands to ( x^2 + 5x + 6 ), but both forms represent the same mathematical relationship. Thus, while the representation changes, the numerical value calculated from the expression does not.
X2 (5)2 = 25 (- 5)2 = 25 An identity, almost, as any number put into this expression will yield the same value.

The algebraic expression of: -x-1y has the same value as -x-y
An equivalent expression.
If x stays the same the expression stays the same. Since the expression involves negative x, the value of the expression decreases as x increases.
You can replace a variable with an equal value or expression. Just make sure the same variable always gets the same value or expression.

++ is an operator that increments the operand. The value of the operand in the expression is incremented first if the ++ is before the operand. The value of the operand in the expression is the same value if the ++ is after the operand.
36.5 is not an exponential expression! Its value is 36.536.5 is not an exponential expression! Its value is 36.536.5 is not an exponential expression! Its value is 36.536.5 is not an exponential expression! Its value is 36.5
