In a shipping container, there are 10 crates. Each crate is filled with 6 boxes and each box is filled with 4 washing machines. A worker removes 1 washing machine from each box. There are no other changes. How many washing machines were removed from the shipping container?
Initially, there were 6 boxes * 4 washing machines per box = 
<gadget id="calculator">6*4</gadget>
<output>24</output>
24 washing machines in each crate.
So there were 24 washing machines per crate * 10 crates = 
<gadget id="calculator">24*10</gadget>
<output>240</output>
240 washing machines in the shipping container.
A worker removes 1 washing machine from each box so there are now 4 original washing machines - 1 removed washing machine = 
<gadget id="calculator">4-1</gadget>
<output>3</output>
3 washing machines in each box.
This means there are 6 boxes * 3 washing machines per box = 
<gadget id="calculator">6*3</gadget>
<output>18</output>
18 washing machines in each crate.
So there are now 18 washing machines per crate * 10 crates = 
<gadget id="calculator">18*10</gadget>
<output>180</output>
180 washing machines in the shipping container.
The difference is how many machine washing machines were removed which is 240 initial washing machines - 180 current washing machines = 
<gadget id="calculator">240-180</gadget>
<output>60</output>
60 washing machines.
