Math is its own language and just like learning any new language, we have to learn how to translate from that language into our own language. Well, in math we have to make sure that we can translate the words of math into expressions and equations and other ways of representing those mathematical concepts. In this lesson, we're going to focus on some of the most common math words. This definitely isn't an entire list of the math words that you can translate, but these are the ones that you'll see most often. In another lesson we'll see how we can actually translate these words into expressions and equations. Whenever you see the words sum of increased by or more than that lets you know that you'll be working with addition. The words difference of or difference between decreased by and less than tell you that you have subtraction. Product of and times let you know that you'll be multiplying and the words quotient of or divided by show you division. Whenever you see the phrase unknown number that lets us know that we need to use a variable. Remember, in math a variable is a letter that represents some number or some quantity but we don't know what that number is. And whenever you see the word is, you can just translate that into an equal sign. For example, if we were to say that x is five, we could just write that as x equal sign five. There are also some math words that are associated with specific numbers. For example, twice or double means that you're multiplying by two and triple means that you're multiplying by three. When you take half of something, you can translate it to multiplying by one half or dividing by two because both of those operations will give you the same result. In a similar way, when you have the phrase a third of something, you can either multiply by one third or divide by three. So now you've learned some of the most common math words that you'll see and it's important to just get comfortable with them and kind of memorize them so that once you do see these in different math problems, you'll know just how to translate them.
