To evaluate an algebraic expression you substitute numbers for variables.

Then follow the order of operations.

Here is a sentence that can help you remember the order of operations.

Evaluate x ? 2xy ? y 2

for x ? 4 and y ? 6. 4 ? 2 4 6 6 2

Substitute 4 for x and 6 for y.

4 ? 2 4 6 ? 36 Evaluate exponents: 6 2 ? 36.

4 ? 48 ? 36 Multiply from left to right.

?8 Add and subtract from left to right. Evaluate each expression for the given values of the variables.

1. a 2

? 2a b 2 ? 3a for a ? 5 and b ? 2 5 2 ? 2 5 2 2 3 5

Substitute 5 for a and 2 for b.

25 + 2

5 4 ? 3 5

Evaluate exponents.

25 ? 40 ? 15

Multiply from left to right.

50

Add and subtract from left to right.

2. c 2 ? cd ? 3d for c ? 7 and d ? 6 7 2 ? 7 6 ? 3 6

Substitute for the variables.

49 ? 7

6 ? 3 6

Evaluate exponents.

49 ? 42 ? 18

Multiply from left to right.
