#### Answer

#Note: $7・7・0 = 7 \times 7 \times 0$
$7 \times 7 \times 0 = 0$

#### Work Step by Step

$a \times b\times c =$ General formula for finding the answer
1. Multiply the first two numbers together $(a \times b)$
$7 \times 7 = 49$
2. Multiply the previous number in Step #1 with the last number
$((a \times b) \times c)$
$49 \times 0 = 0$
**Important: Every time something is multiplied by 0, the answer is 0 and therefore certain steps are not needed to find the answer (In this case, Step #1 is not needed since you know the number will be multiplied by 0)
