you take off the zeros at the end of all the numbers and multiply 1,2,3, and 4 and then add the zeros at the end so you get 24 then adding the zeros you get 240000
Using basic facts can help find the equation mentally. We can do 1 × 2 = 2, then 2 × 3 = 6, then 6 × 4 = 24. Then just add the 0 to 24 to get the answer, 240,000.
