2002 CEMC Gauss (Grade 8) Problems/Problem 2

Problem

The expression $6 \times 1000 + 5 \times 100 + 6 \times 1$ is equivalent to

$\text{ (A) }\ 656 \qquad\text{ (B) }\ 6506 \qquad\text{ (C) }\ 6056 \qquad\text{ (D) }\ 60~506 \qquad\text{ (E) }\ 6560$

Solution

Following order of operations, we have:

$6 \times 1000 + 5 \times 100 + 6 \times 1 = 6000 + 5 \times 100 + 6 \times 1 = 6000 + 500 + 6 \times 1 = 6000 + 500 + 6$

$=6500 + 6 = \boxed {\textbf {(B) } 6506}$
