Answer
#Note: $(a)(b)(c) = a \times b \times c $
$7 \times 1 \times 6 = 42$
Work Step by Step
$a \times b\times c =$ General formula for finding the answer
1. Multiply the first two numbers together $(a \times b)$
$7 \times 1 = 7$
2. Multiply the previous number in Step #1 with the last number
$((a \times b) \times c)$
$7 \times 6 = 42$
