Describe the error in the work shown below. Find an expression equivalent to 18 + 30. Factors of 18: 1, 2, 3, 6, 9, 18Factors of 30:1,2,3,5,6, 10, 15, 3018 + 30 = 6 (3 + 10)

6 (3 + 10) = 6*3 + 6*10 = 18 + 60

As you can see, it's not equivalent to 18+30

To fix it, we can change (3+10) to (3+5)

Now we have 6 (3 + 5). And this is now equivalent to 18+30.
