Step-by-step explanation:

Evaluate Expressions

An algebraic expression consists of a set of variables and constants related by algebraic operations like addition, subtraction, multiplication, etc.

To evaluate an algebraic expression, we replace the variables for the constant value they are assigned.

Let's consider the expression:

$x-y+ z(x + y)$

for x=10, y=-1, z=0

Substituting the variables for their values:

$10-(-1)+ (0)(10 -1)$

$=10+1+ (0)(9)$

$=11+0=11$

The value of the expression is 11
