What that's not a question lol
A single appliance has 6 widgets, and a widget has 7 bolts. Therefore, you need to multiply 6 by 7 to find the number of bolts in a single appliance.
6 x 7 = 42
Now that you know the number of bolts in an appliance, you can find the number of bolts in 20 appliances by multiplying 42 by 20.
42 x 20 = 840
Hence, there are 840 bolts in 20 appliances.
