In other words, we need to add 4 and 2 first, then multiply that number by 5. However, our written expression asks us to multiply 5 by the sum of 4 and 2. This is because the order of operations would call for you to multiply 5 times 4 first, then add 2. However, this wouldn't get us the right answer. If you were to translate this word for word, you'd change the word time s to a multiplication symbol ( ⋅) and put a plus sign ( +) between the four and the two. For instance, some expressions include more than one math operation. Some expressions are slightly more complicated than the ones we looked at on the last page. Have you ever split a check among three people? You could represent the amount of the check with the variable c, and write out that situation as c / 3.Twice as much could be written as 2 ⋅ x, or 2 x.Many of these are probably familiar to you in everyday conversation. Here are some of the most common math words you'll see: ÷and /are just two ways of writing divided. So for instance, four divided by x could be 4 ÷ x. Generally, you'll do this by replacing the words with operators that mean the same thing.

Writing simple expressionsīefore you can tackle complex word problems, you need to know how to translate simple problems into algebra. We'll start with simple word problems, then move on to slightly more complex ones. Others are simple, like descriptions of a math problem. Some word problems have real-life details-almost like a short story. In other words, there are plenty of word problems. If you're learning algebra in school or are studying for a test, you've probably notice that many problems ask you to translate written words into algebraic expressions. en/algebra-topics/reading-algebraic-expressions/content/ Introduction
