How do I evaluate an expression

1. Replace each variable in the expression with the assigned value.

2. Perform the operations in the expression using the correct order of operations.

Step-by-step explanation:

Here's an example. Let's evaluate the expression 2x³ – x² + y

for x = 3 and y = –2.

Replace each variable in the expression with its value. In this example, this means each x becomes a 3 and each y becomes a -2. (It's a good idea to use parentheses to keep track of this.)

So 2(3)³ - (3)² + (-2)

Perform operations with exponents.

2(27) - 9 + (-2)

Perform operations with multiplication and division.

54 - 9 +(-2)

Perform operations with addition and subtraction
