Either of the two above is a correct answer. The number 1 comes first then an unknown number comes in second. 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.
The order here is very important. The first quantity is the number 10 and the second quantity is the unknown number. Instead of "8 plus 9" with two given numbersyou would see, "a number plus 9". This means that an unknown number has been added to Choosing the letter w as our variable, the math phrase above can be expressed as the algebraic expression below.
We will study this in more depth as we get into writing and solving algebraic word problems.
Algebraic Expressions and Key Words for Addition As, you can see from the red, bold words, the key words for addition are: We will divide an unknown number by 7. The last operation that we will study is division. Key words for each operation are indicated in bold.
It means 5 times the unknown number m. In this case, we want to double an unknown value or quantity. The next lesson in this unit is on simplifying algebraic expressions. A quotient is the answer to a division problem. Think of "of" meaning to multiply when you are working with fractions.
Key Words for Division It is time now time to go over some examples to practice writing algebraic expressions. Expressions with More Than One Operation Many people struggle with translating word problems into algebraic expressions.
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.
Examples of How to Translate Basic Math Phrases into Algebraic Expressions We will go over eight 8 examples in this lesson to accommodate two 2 two examples for each operation. This skill will come in handy when working with word problems or real life situations.
We are used to seeing the words, plus, sum, difference, minus, product Please also remember that addition is commutative; therefore, you can reverse the digits and you will end up with the same answer. That means 10 is divided by an unknown number.
For more advanced or slightly complicated expressions, we have a separate lesson for that which is writing multi-part algebraic expressions. Division is not commutative, so you must pay close attention to the order in which you write the expression.
This is mostly used when you are multiplying a fraction times a number. This is a very brief lesson on simple algebraic expressions. Notice that we want to add two quantities: In other words, we are going to subtract the unknown number from the number 8.Translating Words Into an Algebraic Equation and Solving Learning Objectives Translate statements into algebraic equations involving addition, subtraction, multiplication, and division.

A number plus seven. When translating phrases into algebraic expressions, you need to identify keywords and phrases which specifically refer to a mathematical operation (addition, subtraction, multiplication, and division).
Usually, you can write out the algebraic expression of the verbal. Translating Word Problems: Keywords. The hardest thing about doing word problems is using the part where you need to take the English words and translate them into mathematics.
Usually, once you get the math equation, you're fine; the actual math involved is often fairly simple. The third step is to look for "key" words. Certain words. Once you've learned the basic keywords for translating word problems from English into mathematical expressions and equations, you'll be presented with various English expressions, and be told to perform the translation.
Once you've learned to translate phrases into expressions and sentences into equations, you are ready to dive into word. Translate Phrases Worksheets. This translate phrases worksheet will create word problems for the students to translate into an algebraic statements.
