Question

What is the algebraic expression for sum of a number and 10?

Answer 1

`x + 10`

Explanation:

Break down the information given to you to try and identify what the algebraic expression must looks like. You know that you're dealing with

• a sum `->` this means that you are adding something, so you're going to use the `+` sign;

• of a number `->` this means that you're dealing with a variable. The most common notation for a variable is `x`.

• and 10 `->` this is simply an integer that must appear in the algebraic expression along the variable `x`.

So, put all this together to get

`x + 10`

You're adding an unknown number, `x`, to an integer, `10`.
