Selecting the letter m as our variable, the algebraic expression for this math phrase is simply 5 m. It means 5 times the unknown number m. The final answer is 5m. Example 6: Write an algebraic expression for the math phrase ” twice a number”.
In order to write algebraic expressions successfully, you must have some familiarity with fundamental algebraic operations and key terms. For instance, you must know the significance of a variable, which is a letter that acts as a placeholder for an unknown number.
Writing algebraic expressions. A LGEBRA IS A METHOD OF WRITTEN CALCULATIONS that help us reason about numbers. At the very outset, the student should realize that algebra is a skill. And like any skill -- driving a car, baking cookies, playing the guitar -- it requires practice. A lot of practice.
An algebraic expression is a mathematical expression that will have variables, numbers and operations. The variable will represent the number in an expression or an equation. Answers may vary slightly. Being able to write expressions or equations algebraically is a pre algebra concept that is required prior to taking algebra.
