Nollayhtälöiden
Nollayhtälöiden refers to the concept of zero equations in mathematics. A zero equation is an equation that is always true, regardless of the values of the variables involved. These are also known as identities. A common example is $x + 0 = x$, which holds true for any number $x$. Another example is $a(b+c) = ab + ac$, which is the distributive property and is always valid.
Zero equations are fundamental in algebra and serve as building blocks for simplifying expressions and solving
In contrast to conditional equations, which are only true for specific values of the variables (like $2x
