Question: How am I supposed to know whats $16 + f + 7$?
1. The problem is to simplify the expression $16 + f + 7$.
2. The formula used here is the addition of like terms and constants.
3. First, add the constants $16$ and $7$ together: $$16 + 7 = 23$$
4. Now rewrite the expression with the sum of constants and the variable term: $$23 + f$$
5. Since $f$ is a variable and cannot be combined with the constant $23$, the simplified expression is $$23 + f$$.
This is the simplest form of the expression.
