Represent the following phrase as an algebraic expression, where "a number" is the letter x. You do not need to simplify. \[ 2 \text { is subtracted from twice a number. } \]

To represent the phrase "2 is subtracted from twice a number" as an algebraic expression, we can break it down. "Twice a number" translates to \( 2x \), and "2 is subtracted from" implies we take away 2 from that expression. Therefore, the algebraic expression is: \[ 2x - 2 \] Now, don't forget that in algebra, phrases can often sound a bit like riddles. Breaking them down step by step, like this, makes it much easier to solve! And remember, math often mirrors real-life situations. When you subtract, you're essentially saying you have something and you're taking part of it away—something that happens every day, whether you're spending money or sharing snacks with friends!
