All the symbols you write in math are just a language or short-hand to represent real-world ideas. In this tutorial, we'll look at some of the short-hand including variables, expression terms, factors and coefficients. Mostly, however, we'll get experience writing algebraic expressions that elegantly represent real-life ideas. Common Core Standard: 6.EE.A.2, 6.EE.A.2b
Our focus here is understanding that a variable is just a symbol that can represent different values in an expression. We got this. Just watch.
Great question. In algebra, we do indeed avoid using the multiplication sign. We'll explain it for you here.
Think of an expression as a sentence. A sentence has parts, and so does an expression. We think this is going to make sense, but take your time and pause if necessary!
Can you write the algebraic expressions that represent what these statements are saying? Sure you can! We'll help you.
Write a mathematical expression from a sentence.
These sentences describe or represent algebraic expressions. See if you can translate them for solving. We'll do it together.
Like other exercises in this tutorial, we're rewriting statements into algebraic expression. This time we have to choose which is the correct one among those given.
Write a mathematical expression from sentences. Requires distribution.
Here we interpret data in a table and solve a word problem by writing an algebraic expression.
We're writing an expression to answer a word problem about butter. Could there be a better reason to do this?
The more you practice, the better you get at writing algebraic expressions. So don't hesitate. Let's go!
