We are used to seeing the words, plus, sum, difference, minus, product Play close attention to the order in which it is written.

The difference between a numerical expression and an algebra expression is that we will be using variables when writing an algebraic expression. Division is not commutative, so you must pay close attention to the order in which you write the expression.

This means that an unknown number has been added to The next lesson in this unit is on simplifying algebraic expressions. The key words are: In other words, we are going to subtract the unknown number from the number 8.

We will divide an unknown number by 7. In this case, we want to double an unknown value or quantity. This is mostly used when you are multiplying a fraction times a number. You are probably very used to translating words into numerical expressions.

This skill will come in handy when working with word problems or real life situations. While the quantity that comes after it becomes the minuend.

One of the most important things to remember is to look for key words and to make sure that your expression matches the context of the word problem.

Selecting the letter m as our variable, the algebraic expression for this math phrase is simply 5m. In addition, when you encounter this math word difference make sure to pay attention to the order. Remember that subtraction is not commutative, so the order in which write the digits does matter!

Please also remember that addition is commutative; therefore, you can reverse the digits and you will end up with the same answer. Algebraic Expressions and Key Words for Addition As, you can see from the red, bold words, the key words for addition are: Let c be the unknown number, the algebraic expression for the math phrase above can be written as You might also be interested in: Notice that we want to add two quantities: The order here is very important.

Either of the two above is a correct answer. 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. To find the product of two quantities or values, it means that we will multiply them together.

A quotient is the answer to a division problem. This is a very brief lesson on simple algebraic expressions. Key words for each operation are indicated in bold. You may use any letters of the alphabet. This will help you to easily translate the expression.

The first quantity is the number 10 and the second quantity is the unknown number. For more advanced or slightly complicated expressions, we have a separate lesson for that which is writing multi-part algebraic expressions.

Instead of "8 plus 9" with two given numbersyou would see, "a number plus 9". That means the number 1 is the minuend and the unknown number is the subtrahend.

Take a look at these few examples: Think of "of" meaning to multiply when you are working with fractions. This is most important for operations that are not commutative, such as subtraction and division.TRANSLATING KEY WORDS AND PHRASES INTO ALGEBRAIC EXPRESSIONS The table below lists some key words and phrases that are used to describe common mathematical operations.

To write algebraic expressions and equations, assign a variable to represent the unknown number. Translating Words into Algebraic Expressions Operation Word Expression Algebraic Expression Addition Add, Added to, the sum of, more than, increased by, the total of.

Translating Basic Math Phrases into Algebraic Expressions There is no single strategy for translating math phrases into algebraic expressions. As long as you can remember the basics, you should be able to tackle the more challenging ones. Translating Words Into an Algebraic Equation and Solving.
