How do you translate an English statement into an algebraic expression?
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 description in the order that it is said.
What is algebraic expression examples?
Algebraic expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division). For example, 2(x + 8y) is an algebraic expression.
What is an algebraic term?
In Algebra a term is either a single number or variable, or numbers and variables multiplied together. Terms are separated by + or − signs, or sometimes by divide. See: Variable.
What is the algebraic form?
Definition of algebraic form : a homogeneous rational integral function of two or more variables.
How is an algebraic representation of a translation used?
ALGEBRAIC REPRESENTATIONS OF TRANSLATIONS To translate a figure in the coordinate plane, we have to translate each of its vertices. Then, we have to connect the vertices to form the image. We can use the rules shown in the table which describe how coordinates change when a figure is translated right, left, up, and down on the coordinate plane.
How to represent the translation of 4 units?
Let A’, B’ and C’ be the vertices of the translated figure. Since there is a translation of 4 units to the right and 1 unit up, we have to add 4 to x-coordinate and add 1 to y-coordinate of each vertex.
How are numerical expressions different from Algebra 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. The difference between a numerical expression and an algebra expression is that we will be using variables when writing an algebraic expression.
What are the key words for subtraction in Algebra?
Our key words for subtraction are: minus, less, subtract, decrease, younger than, and lowered. 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.
