Write an expression that represents subtracting 12 from 𝑦.

Let’s read carefully, our expression should show subtracting 12 from 𝑦. Subtracting 12 means taking 12 away from an amount we already have. We already have 𝑦, so we wanna take away 12 from 𝑦. You have 𝑦, we’re going to take away, or subtract, 12. An expression that represents subtracting 12 from 𝑦 would look like this: 𝑦 minus 12.
