How to Write Math Expressions or Equations as Sentences - Expressions are where students often get lost. It is not easy to convert math expressions or equations into sentences. It can be a bit tricky to articulate the data which is presented by the math equations and expressions. So, when we are writing a word problem, we need to be familiar with the terminologies that are used in defining a particular action that is taking place in that equation. The same basic principles apply to all the different forms of expressions that need to be evaluated: absolute values, exponentials, and factorials. Here is an example of written expressions that denote that something is equal: - Is the same as, - Will be, - Was, - Gives, - Is, - Is equal to Let's understand it with an example: Translate the expression 6 + 9 = 15 The translation would be, the sum of 6 and 9 is equals to 15. There are two expressions in this sentence that have been used to translate the equation. It is equal to which denotes ‘=' and sum of ‘+.'
