This skill will come in handy when working with word problems or real life situations.

Pay close attention to the "key words" that represent mathematical operations. You are probably very used to translating words into numerical expressions. We are used to seeing the words, plus, sum, difference, minus, product The good news is that these very same words that we use to write numerical expressions are going to be used to write algebra expressions.

The difference between a numerical expression and an algebra expression is that we will be using variables when writing an algebraic expression. Instead of "8 plus 9" with two given numbersyou would see, "a number plus 9".

We don't know exactly "what number", so we would use a variable to indicate that it can be any number.

Key words for each operation are indicated in bold. This will help you to easily translate the expression. Algebraic Expressions and Key Words for Addition As, you can see from the red, bold words, the key words for addition are: Please also remember that addition is commutative; therefore, you can reverse the digits and you will end up with the same answer.

Now, let's take a look at the key words for subtraction. Remember that subtraction is not commutative, so the order in which write the digits does matter! Now we'll take a look at key words for multiplication word problems.

Of is the tricky word. This is mostly used when you are multiplying a fraction times a number. Think of "of" meaning to multiply when you are working with fractions. The last operation that we will study is division. Division is not commutative, so you must pay close attention to the order in which you write the expression.

The key words are: Play close attention to the order in which it is written. Quotient is also a key word for division.Write a verbal expression for each algebraic expression.
