Problem 1

Which of the following values is largest?

$\textbf{(A) }2+0+1+7\qquad\textbf{(B) }2 \times 0 +1+7\qquad\textbf{(C) }2+0 \times 1 + 7\qquad\textbf{(D) }2+0+1 \times 7\qquad\textbf{(E) }2 \times 0 \times 1 \times 7$

Solution 1

We compute each expression individually according to the order of operations. We get $2 + 0 + 1 + 7 = 10$, $2 \times 0 + 1 + 7 = 8$, $2 + 0 \times 1 + 7 = 9$, $2 + 0 + 1 \times 7 = 9$, and $2 \times 0 \times 1 \times 7 = 0$. Since $10$ is the greatest out of these numbers, $\boxed{\textbf{(A) }2+0+1+7}$ is the answer.

Solution 2

We immediately see that every one of the choices, except for A, has a number multiplied by $0$. This will only make the expression's value smaller. Therefore, $\boxed{\textbf{(A) }2+0+1+7}$ is your answer
