The image you uploaded contains an algebraic expression with a combination of variables and operations. Here’s the expression from the image:

[ \left[ \left( x \times (1 + y) \right) - \left( y \times (1 + z) \right) \right] - \left[ \frac{x - y}{f} \right] ] $\div \left( f \times (1 + i) \right)$

This looks like a complex equation involving multiple terms, including variables like $x$, $y$, $z$, $f$, and $i$, with operations like multiplication, subtraction, and division.
