It's like they didn't want to commit to a full relationship!</p>
<p>Some examples would be:</p>
<ul>
<li>$4x$</li>
<li>$2x+3$ — note that all the pieces do not need to have a variable (sometimes numbers just want to hang out with letters).</li>
<li>$7y + 2y$</li>
<li>$y^3-y$ — note that the variable $y$ can be raised to powers (power to the $y$!).</li>
<li>$x+y-z$ — note that we can mix variables (a regular math party).</li>
<li>$3x^5+48m^2-37z^{-2}$ — even this horrendous expression is valid! (It's the math equivalent of a chaotic family reunion).</li>
</ul>
<p>Algebraic expressions might look like a random assortment of numbers and letters, but they have their own kind of order. Just think of them as the free-spirited artists of the math world, creating without the constraints of an equals sign.</p>
